Kaushik Lingarkar 82b5aaf7e3 Introduce core.trustPackedRefsStat config
Currently, we always read packed-refs file when 'trustFolderStat'
is false. Introduce a new config 'trustPackedRefsStat' which takes
precedence over 'trustFolderStat' when reading packed refs. Possible
values for this new config are:

* always: Trust packed-refs file attributes
* after_open: Same as 'always', but refresh the file attributes of
              packed-refs before trusting it
* never: Always read the packed-refs file
* unset: Fallback to 'trustFolderStat' to determine if the file
  attributes of packed-refs can be trusted

Folks whose repositories are on NFS and have traditionally been
setting 'trustFolderStat=false' can now get some performance improvement
with 'trustPackedRefsStat=after_open' as it refreshes the file
attributes of packed-refs (at least on some NFS clients) before
considering it.

For example, consider a repository on NFS with ~500k packed-refs. Here
are some stats which illustrate the improvement with this new config
when reading packed refs on NFS:

trustFolderStat=true trustPackedRefsStat=unset: 0.2ms
trustFolderStat=false trustPackedRefsStat=unset: 155ms
trustFolderStat=false trustPackedRefsStat=after_open: 1.5ms

Matthias Sohn 59029aec30 Add option to allow using JDK's SHA1 implementation
The change If6da9833 moved the computation of SHA1 from the JVM's
JCE to a pure Java implementation with collision detection.
The extra security for public sites comes with a cost of slower
SHA1 processing compared to the native implementation in the JDK.

When JGit is used internally and not exposed to any traffic from
external or untrusted users, the extra cost of the pure Java SHA1
implementation can be avoided, falling back to the previous
native MessageDigest implementation.

Saša Živkov cb90ed0852 Allow to perform PackedBatchRefUpdate without locking loose refs
Add another newBatchUpdate method in the RefDirectory where we can
control if the created PackedBatchRefUpdate will lock the loose refs or
not.

This can be useful in cases when we run programs which have exclusive
access to a Git repository and we know that locking loose refs is
unnecessary and just a performance loss.

Thomas Wolf a8e683fef6 [merge] Fix merge conflicts with symlinks
Previous code would do a content merge on symlinks, and write the merge
result to the working tree as a file. C git doesn't do this; it leaves
a symlink in the working tree unchanged, or in a delete-modify conflict
it would check out "theirs".

Moreover, previous code would write the merge result to the link target,
not to the link. This would overwrite an existing link target, or fail
if the link pointed to a directory.

In link/file conflicts or file/link conflicts, C git always puts the
file into the working tree.

Change conflict handling accordingly. Add tests for all the conflict
cases.

Han-Wen Nienhuys 6d2bcb6043 DirCacheCheckout#getContent: also take InputStream supplier
This lets us use DirCacheCheckout for routines that want to write
files in the worktree that aren't available as a git object.

DirCacheCheckout#getContent takes a InputStream supplier rather than
InputStream: if filtering fails with IOException, the data is placed
unfiltered in the checkout. This means that the stream has to be read
again, from the start.

Use it in this way in ApplyCommand. This use is incorrect, though: the
same InputStream is returned twice, so if the read to be retried, the
stream will return 0 bytes. It doesn't really matter, because in
either case, the SHA1 will not match up, and the patch fails.
