archive: Drop unnecessary empty comments and 'final' qualifiers on locals
Early JGit code used comments to inform the Eclipse formatter about
where to break lines and used final in the hope of making code faster.
The ArchiveCommand command implementation imitated that style.
Nowadays the project relies less on the Eclipse formatter and relies
more on Java having sane performance with local variables that are not
explicitly marked 'final'. Removing the unnecessary empty comments and
'final' qualifiers makes this code more readable and more consistent
with recent JGit code.

Close 'out' consistently in ArchiveCommand.call
Whether the output stream specified with setOutputStream() is closed by
ArchiveCommand.call() is murky and inconsistent:
- on success, it is closed
- if an exception is encountered when writing the archive, it is closed
- if an exception is encountered when calling createArchiveStream to
open the archive, we forget to close it
Close the output stream consistently to avoid leaks.
Now that the inner try-with-resources doesn't have its own finally
block, this allows us to merge the two try blocks.
It would be even better to never close the output stream. That will
involve more API changes to avoid silently breaking callers, so it is
deferred to a later change.

Fix that exceptions in ReceivePack cause Invalid Channel 101 exceptions
When during a PushOperation the server hits an exception different from
UnpackException the JGit server behaved wrong. That kind of exceptions
are handled so late that the connection is already released and the
information whether to talk sideband to the client is lost. In detail:
ReceivePack.receive() will call release() and that will reset the
capabilities. But later on the stack in ReceivePackServlet.doPost() it
is tried to send a response to client now with reset capabilities (no
sideband!).

Better report too large pack-files from PushCommand
JGits PushCommand and BasePackPushConnection were throwing generic
TransportExceptions when the pushed pack-file was rejected by the server
since it was too big. Let JGit better interprete the server's response
to detect this situation and throw a more specific exception.
This detection works by parsing the status line sent by the server. This
change only recognizes the response sent by a JGit based server. All
other servers which report such problems in a different way still lead
to a generic TransportExceptions.

InterruptedIOException was thrown and the pack file was marked as

Use ANY_DIFF filter in ResolveMerger only for bare repositories
As Chris pointed out change I822721c76c64e614f87a080ced2457941f53adcd
slowed down merge since ANY_DIFF filter is much less efficient than the
manual detection of diffs done in ResolveMerger.processEntry() since it
avoids unnecessary filesystem calls using the git index. Hence only set
the ANY_DIFF filter on bare repositories which don't have a working tree
to scan.
To test performance I used the setup described in Chris' comment on
change I822721c76c64e614f87a080ced2457941f53adcd and modified
ResolveMerger.mergeTrees() to not add the working tree in order to

At least on Mac I couldn't detect a speedup, with and without the
ANY_DIFF filter merge test takes an average 0.67sec.

Avoid always calling `sh -c umask` on startup, instead deferring

use the execute bit. This allows servers using bare repos to avoid
a costly fork+exec for a value that is never used.
Store the umask as an int instead of two Boolean. This is slightly
smaller memory (one int vs. two references) and makes it easier for
an application to force setting the umask to a value that overrides
whatever the shell told JGit.
Simplify the code to bail by returning early when canExecute is
false, which is the common case for working tree files.
