To prepare for some structs and constants being moved from
builtin/apply.c to apply.h, we should give them some more
specific names to avoid possible name collisions in the global
namespace.

To libify `git apply` functionality we must make 'struct apply_state'
usable outside "builtin/apply.c".
Let's do that by creating a new "apply.h" and moving
'struct apply_state' there.

To libify `git apply` functionality we have to signal errors
to the caller instead of die()ing.
As a first step in this direction, let's make apply_patch() return
-1 or -128 in case of errors instead of dying. For now its only
caller apply_all_patches() will exit(128) when apply_patch()
return -128 and it will exit(1) when it returns -1.
We exit() with code 128 because that was what die() was doing
and we want to keep the distinction between exiting with code 1
and exiting with code 128.

To libify `git apply` functionality we have to signal errors to the
caller instead of die()ing.
To do that in a compatible manner with the rest of the error handling
in builtin/apply.c, let's make find_header() return -128 instead of
calling die().
We could make it return -1, unfortunately find_header() already
returns -1 when no header is found.

To libify `git apply` functionality we have to signal errors to the
caller instead of die()ing or exit()ing.
To do that in a compatible manner with the rest of the error handling
in builtin/apply.c, parse_chunk() should return a negative integer
instead of calling die() or exit().
As parse_chunk() is called only by apply_patch() which already
returns either -1 or -128 when an error happened, let's make it also
return -1 or -128.
This makes it compatible with what find_header() and parse_binary()
already return.

To libify `git apply` functionality we have to signal errors to the
caller instead of die()ing.
To do that in a compatible manner with the rest of the error handling
in builtin/apply.c, parse_single_patch() should return a negative

Let's do that by using error() and let's adjust the related test
cases accordingly.

To libify `git apply` functionality we must make init_apply_state()
usable outside "builtin/apply.c".
Let's do that by moving it into a new "apply.c".

To finish libifying the apply functionality, apply_all_patches() should not
die() or exit() in case of error, but return either 128 or 1, so that it
gives the same exit code as when die() or exit(1) is called. This way
scripts relying on the exit code don't need to be changed.
While doing that we must take care that file descriptors are properly closed
and, if needed, reset to a sensible value.
Also, according to the lockfile API, when finished with a lockfile, one
should either commit it or roll it back.
This is even more important now that the same lockfile can be passed
to init_apply_state() many times to be reused by series of calls to
the apply lib functions.

The gitdiff_*() functions that are called as p->fn() in parse_git_header()
should return 1 instead of -1 in case of end of header or unrecognized
input, as these are not real errors. It just instructs the parser to break
out.
This makes it possible for gitdiff_*() functions to return -1 in case of a
real error. This will be done in a following patch.

To libify `git apply` functionality we have to signal errors to the
caller instead of die()ing.
To do that in a compatible manner with the rest of the error handling
in "builtin/apply.c", gitdiff_*() functions should return -1 instead
of calling die().
A previous patch made it possible for gitdiff_*() functions to
return -1 in case of error. Let's take advantage of that to
make gitdiff_verify_name() return -1 on error, and to have
gitdiff_oldname() and gitdiff_newname() directly return
what gitdiff_verify_name() returns.

To libify `git apply` functionality we have to signal errors to the
caller instead of die()ing.
To do that in a compatible manner with the rest of the error handling
in "builtin/apply.c", die_on_unsafe_path() should return a negative
integer instead of calling die(), so while doing that let's change
its name to check_unsafe_path().

To libify `git apply` functionality we have to signal errors to the
caller instead of exit()ing.
To do that in a compatible manner with the rest of the error handling
in "builtin/apply.c", create_file() should just return what
add_conflicted_stages_file() and add_index_file() are returning
instead of calling exit().

To libify `git apply` functionality we have to signal errors to the
caller instead of die()ing.
To do that in a compatible manner with the rest of the error handling
in "builtin/apply.c", try_create_file() should return -1 in case of
error.
Unfortunately try_create_file() currently returns -1 to signal a
recoverable error. To fix that, let's make it return 1 in case of
a recoverable error and -1 in case of an unrecoverable error.

As these functions are going to be part of the libified
apply API, let's give them a name that is more specific
to the apply API.

The constants for the "inaccurate-eof" and the "recount" options will
be used in both "apply.c" and "builtin/apply.c", so they need to go
into "apply.h", and therefore they need a name that is more specific
to the API they belong to.

Some parsing functions that were used in both "apply.c" and
"builtin/apply.c" are now only used in the former, so they
can be made static to "apply.c".

To avoid possible mistakes and to uniformly show the errno
related messages, let's use error_errno() where possible.

This changes 'int apply_verbosely' into 'enum apply_verbosity', and
changes the possible values of the variable from a bool to
a tristate.
The previous 'false' state is changed into 'verbosity_normal'.
The previous 'true' state is changed into 'verbosity_verbose'.
The new added state is 'verbosity_silent'. It should prevent
anything to be printed on both stderr and stdout.
This is needed because `git am` wants to first call apply
functionality silently, if it can then fall back on 3-way merge
in case of error.
Printing on stdout, and calls to warning() or error() are not
taken care of in this patch, as that will be done in following
patches.

When apply_verbosity is set to verbosity_silent nothing should be
printed on both stderr and stdout.
To avoid printing on stdout, we can just skip calling the following
functions:
- stat_patch_list(),
- numstat_patch_list(),
- summary_patch_list().
It is safe to do that because the above functions have no side
effects other than printing:
- stat_patch_list() only computes some local values and then call
show_stats() and print_stat_summary(), those two functions only
compute local values and call printing functions,
- numstat_patch_list() also only computes local values and calls
printing functions,
- summary_patch_list() calls show_file_mode_name(), printf(),
show_rename_copy(), show_mode_change() that are only printing.

There are already set_die_routine() and set_error_routine(),
so let's add set_warn_routine() as this will be needed in a
following commit.

Let's make it possible to get the current error_routine and warn_routine,
so that we can store them before using set_error_routine() or
set_warn_routine() to use new ones.
This way we will be able put back the original routines, when we are done
with using new ones.

To avoid printing anything when applying with
`state->apply_verbosity == verbosity_silent`, let's save the
existing warn and error routines before applying, and let's
replace them with a routine that does nothing.
Then after applying, let's restore the saved routines.
Note that, as we need to restore the saved routines in all
cases, we cannot return early any more in apply_all_patches().

Parsing `git apply` options can be useful to other commands that
want to call the libified apply functionality, because this way
they can easily pass some options from their own command line to
the libified apply functionality.
This will be used by `git am` in a following patch.
To make this possible, let's refactor the `git apply` option
parsing code into a new libified apply_parse_options() function.
Doing that makes it possible to remove some functions definitions
from "apply.h" and make them static in "apply.c".

To libify git apply functionality, we will need to read from a
different index file in get_current_sha1(). This index file will be
stored in "struct apply_state", so let's pass the state to
build_fake_ancestor() which will later pass it to get_current_sha1().

Sometimes we want to apply in a different index file.
Before the apply functionality was libified it was possible to
use the GIT_INDEX_FILE environment variable, for this purpose.
But now, as the apply functionality has been libified, it should
be possible to do that in a libified way.

This replaces run_apply() implementation with a new one that
uses the apply API that has been previously prepared in
apply.c and apply.h.
This shoud improve performance a lot in certain cases.
As the previous implementation was creating a new `git apply`
process to apply each patch, it could be slow on systems like
Windows where it is costly to create new processes.
Also the new `git apply` process had to read the index from
disk, and when the process was done the calling process
discarded its own index and read back from disk the new
index that had been created by the `git apply` process.
This could be very inefficient with big repositories that
have big index files, especially when the system decided
that it was a good idea to run the `git apply` processes on
a different processor core.
Also eliminating index reads enables further performance
improvements by using:
`git update-index --split-index`
For example here is a benchmark of a multi hundred commit
rebase on the Linux kernel on a Debian laptop with SSD:
command: git rebase --onto 1993b17 52bef0c 29dde7c
Vanilla "next" without split index: 1m54.953s
Vanilla "next" with split index: 1m22.476s
This series on top of "next" without split index: 1m12.034s
This series on top of "next" with split index: 0m15.678s
(using branch "next" from mid April 2016.)

The previous three lines are white space broken AFAICT. The seem to be
white space broken in the original location as well, so no need for a reroll
just for this. But in case you do a reroll, you may want to fix these
on the fly?

These three functions seem slightly different, not just moved.
Oh you removed the static key word!
Apart from the one minor nit and the removal of the static keyword,
the rest is just moved code.
