vcs-svn: make reading of properties binary-safe

svn-fe errors out on revision 59151 of the ASF repository:

 fatal: invalid dump: unexpected end of file

The proximate cause is a property with an embedded NUL character.
Previously such anomalies were ignored but commit c9d1c8ba
(2010-12-28) introduced a check strlen(val) == len to avoid reading
uninitialized data when a property list ends early and unfortunately
this test does not distinguish between "foo" followed by EOF and the
string "foo\0bar\0baz".

Fix it by using buffer_read_binary to read to a strbuf and checking
the actual length read.  Most consumers of properties still use
C-style strings, so in practice an author or log message with embedded
NULs will be truncated, but a least this way svn-fe won't error out

gitweb: Fix handling of fractional timezones in parse_date

Fractional timezones, like -0330 (NST used in Canada) or +0430
(Afghanistan, Iran DST), were not handled properly in parse_date; this
means values such as 'minute_local' and 'iso-tz' were not generated
correctly.

This was caused by two mistakes:

* sign of timezone was applied only to hour part of offset, and not
  as it should be also to minutes part (this affected only negative
  fractional timezones).

* 'int $h + $m/60' is 'int($h + $m/60)' and not 'int($h) + $m/60',
  so fractional part was discarded altogether ($h is hours, $m is
  minutes, which is always less than 60).

Note that positive fractional timezones +0430, +0530 and +1030 can be
found as authortime in git.git repository itself.

For example http://repo.or.cz/w/git.git/commit/88d50e7 had authortime
of "Fri, 8 Jan 2010 18:48:07 +0000 (23:48 +0530)", which is not marked
with 'atnight', when "git show 88d50e7" gives correct author date of
"Sat Jan 9 00:18:07 2010 +0530".

rerere: make sure it works even in a workdir attached to a young repository

The git-new-workdir script in contrib/ makes a new work tree by sharing
many subdirectories of the .git directory with the original repository.
When rerere.enabled is set in the original repository, but the user has
not encountered any conflicts yet, the original repository may not yet
have .git/rr-cache directory.

When rerere wants to run in a new work tree created from such a young
original repository, it fails to mkdir(2) .git/rr-cache that is a symlink
to a yet-to-be-created directory.

There are three possible approaches to this:

 - A naive solution is not to create a symlink in the git-new-workdir
   script to a directory the original does not have (yet).  This is not a
   solution, as we tend to lazily create subdirectories of .git/, and
   having rerere.enabled configuration set is a strong indication that the
   user _wants_ to have this lazy creation to happen;

 - We could always create .git/rr-cache upon repository creation.  This is
   tempting but will not help people with existing repositories.

 - Detect this case by seeing that mkdir(2) failed with EEXIST, checking
   that the path is a symlink, and try running mkdir(2) on the link
   target.

This patch solves the issue by doing the third one.

Strictly speaking, this is incomplete.  It does not attempt to handle
relative symbolic link that points into the original repository, but this
is good enough to help people who use contrib/workdir/git-new-workdir
script.

checkout: clear commit marks after detached-orphan check

When leaving a detached HEAD, we do a revision walk to make
sure the commit we are leaving isn't being orphaned.
However, this leaves crufty marks in the commit objects
which can confuse later walkers, like the one in
stat_tracking_info.

Let's clean up after ourselves to prevent this conflict.

does it by adding something like below to HTML head:

  <base href="http://HOST/gitweb.cgi">

This breaks the "patch" anchor links seen on the commitdiff pages,
because these links, being relative (<a href="#patch1">), are resolved
(computed) relative to the base URL and not relative to current URL,
i.e. as:

  http://HOST/gitweb.cgi#patch1

  http://HOST/gitweb.cgi/myproject.git/commitdiff/35a9811ef9d68eae9afd76bede121da4f89b448c#patch1

Add an "-anchor" parameter to href(), and use href(-anchor=>"patch1")
to generate "patch" anchor links, so that the full path is included in
the patch link.

  print "foo";

to

  print "foo" .

run-command: prettify -D_FORTIFY_SOURCE workaround

Current gcc + glibc with -D_FORTIFY_SOURCE try very aggressively to
protect against a programming style which uses write(...) without
checking the return value for errors.  Even the usual hint of casting
to (void) does not suppress the warning.

Sometimes when there is an output error, especially right before exit,
there really is nothing to be done.  The obvious solution, adopted in
v1.7.0.3~20^2 (run-command.c: fix build warnings on Ubuntu,
2010-01-30), is to save the return value to a dummy variable:

ssize_t dummy;
dummy = write(...);

But that (1) is ugly and (2) triggers -Wunused-but-set-variable
warnings with gcc-4.6 -Wall, so we are not much better off than when
we started.

Instead, use an "if" statement with an empty body to make the intent
clear.

if (write(...))

mktag: avoid %td in format string

Since v1.7.0-rc0~34 (make "mktag" a built-in, 2010-01-22), git mktag
uses the C99-style %td format to print ptrdiff_t values.  It falls
back to %d when NO_C99_FORMAT is set, on the assumption that pre-C99
systems probably are using 32-bit pointers.

But many modern systems are 64-bit and

 * sometimes one wants to test the NO_C99_FORMAT fallbacks using a
   modern development platform;
 * some platforms (I'm looking at you, msvc) have not gotten with the
   program and are still C89-only.

These ptrdiff_t values are offsets from the beginning of a buffer, so
a size_t or uintmax_t would work about as well.  Use the latter so we
can take advantage of the PRIuMAX fallback in git-compat-util.h, even
on C99-challenged systems with 64-bit pointers.
