[PATCH v4 00/21] [Outreachy] Move doc to header files

["Heba Waly via GitGitGadget" <gitgitgadget@gmail.com>]

Move the documentation from Documentation/technical/api-*.txt to the
corresponding header file, as it's easier for the developers to find the
usage information beside the code instead of looking for it in another doc
file.

Also documentation/technical/api-*.txt is removed because the information it
has is will be redundant and it'll be hard to keep it up to date and
synchronized with the documentation in the header files.

api-trace2.txt is not removed because it has lots of valuable information
that seems more appropriate to be in a separate doc file not in the trace2.h
although the functions documentation is moved to the trace2.h

api-error-handling.txt is not removed as well because no other file seemed
to be more suitable for the doc it contains. I'm open to suggestions though.

The ll-merge related doc was removed from api-merge.txt to ll-merge.h, while
the rest of the file is left as is.
