[PATCH v4 0/2] allow git-svn fetching to work using serf

["Kyle J. McKay" <mackyle@gmail.com>]

This patch allows git-svn to fetch successfully using the
serf library when given an https?: url to fetch from.

Unfortunately some svn servers do not seem to be configured
well for use with the serf library.  This can cause fetching
to take longer compared to the neon library or actually
cause timeouts during the fetch.  When timeouts occur
git-svn can be safely restarted to fetch more revisions.

A new temp_is_locked function has been added to Git.pm
to facilitate using the minimal number of temp files
possible when using serf.

The problem that occurs when running git-svn fetch using
the serf library is that the previously used temp file
is not always unlocked before the next temp file needs
to be used.

To work around this problem, a new temp name is used
if the temp name that would otherwise be chosen is
currently locked.

Versions v2-v3 of the patch introduced a bug when attempting
to change the _temp_cache function to use the new
temp_is_locked function at the suggestion of a reviewer.

This version reverts that as the logic in _temp_cache isn't
really conducive to that change because of the tests it makes
and the change was causing problems.

This is the single change that is reverted in Git.pm 
compared to v3 of the patch:

diff --git a/perl/Git.pm b/perl/Git.pm

-		if (temp_is_locked($name)) {
+		if ($TEMP_FILES{$$temp_fd}{locked}) {
 			throw Error::Simple("Temp file with moniker '" .
 				$name . "' already in use");
 		}


Other than that single change, this patch series is identical to v3,
and in particular the 0002 perl/Git/SVN/Fetcher.pm change is identical
to that of v3.
