gitweb: Cleanup git_print_log()

When we see a signed-off-by line (and its friends), we set $signoff
to true, but then we process the next line after we are done without
giving control to the rest of the loop.  And when the line we saw is
not a signed-off-by line, we reset $signoff to false before running
the remainder of the loop.

Hence, the check for $signoff that attempts to remove an extra empty
line between two signed-off-by line was not doing anything useful.

Rename $empty to a more explicit name $skip_blank_line to tell us to
skip a blank line when we see one, set it after we see and emit a
blank line (to avoid showing more than one empty lines in a raw) or
after we handle a signed-off-by line (to avoid empty lines after
such a line), to fix this bug, and get rid of the $signoff variable
that is not useful.

gitweb: Handle other types of tag in git_print_log

There are many types of tags used in S-o-b area [1].
Update the regex to handle them properly. It requires
the tag should be started by a capital letter and ended
by '-by: ' or '-By: '. The only exception is 'Cc: '.

gitweb: Add support to Link: tag

The tip tree is the one of major subsystem tree in the
Linux kernel project. On the tip tree, the Link: (or
similar Buglink:) tag is used for tracking the original
discussion or context. Since it's ususally in the S-o-b
area, it'd be better using same style with others.

Also as it tends to contain a message-id sent from git
send-email, a part of the line would set a wrong hyperlink
like [1]. Fix it by not using format_log_line_html().

git p4: refactor diffOpts calculation

P4Submit.applyCommit()

To avoid recalculating the same diffOpts for each commit, move it
out of applyCommit() and into the top-level run().  Also fix a bug
in that code which interpreted the value of detectRenames as a
string rather than as a boolean.

index-pack: loop while inflating objects in unpack_data

When the unpack_data function is given a consume() callback,
it unpacks only 64K of the input at a time, feeding it to
git_inflate along with a 64K output buffer.  However,
because we are inflating, there is a good chance that the
output buffer will fill before consuming all of the input.
In this case, we need to loop on git_inflate until we have
fed the whole input buffer, feeding each chunk of output to
the consume buffer.

The current code does not do this, and as a result, will
fail the loop condition and trigger a fatal "serious inflate
inconsistency" error in this case.

While we're rearranging the loop, let's get rid of the
extra last_out pointer. It is meant to point to the
beginning of the buffer that we feed to git_inflate, but in
practice this is always the beginning of our same 64K
buffer, because:

  1. At the beginning of the loop, we are feeding the
     buffer.

  2. At the end of the loop, if we are using a consume()
     function, we reset git_inflate's pointer to the
     beginning of the buffer.  If we are not using a
     consume() function, then we do not care about the value
     of last_out at all.

cache_name_compare(): do not truncate while comparing paths

We failed to use ce_namelen() equivalent and instead only compared
up to the CE_NAMEMASK bytes by mistake.  Adding an overlong path
that shares the same common prefix as an existing entry in the index
did not add a new entry, but instead replaced the existing one, as
the result.
