sendfile() does the same job and avoids to copy the content into userland
and back. One has to define NO_SENDFILE in case the OS (kernel / libc)
does not supported. It is disabled by default on non-linux environemnts.
According to the glibc, sendfile64() was added in Linux 2.4 (so it has
been there for a while) but after browsing over the mapage of FreeBSD's I
noticed that the prototype is little different.

Everything works just bumping the version in Makefile and commit hash
in submodule. No code changes required.

Locally installed packages are usually installed to /usr/local.
Packagers can use `make prefix=/usr` to get back the old behavior.

My dmesg is filled with the oom killer bringing down processes while the
Bingbot downloads every snapshot for every commit of the Linux kernel in
tar.xz format. Sure, I should be running with memory limits, and now I'm
using cgroups, but a more general solution is to prevent crawlers from
wasting resources like that in the first place.

This adds a favicon to cgit. It is not enabled by default, though.
The file contains two icons, 16x16 and 32x32 pixels, optimized for size.

Features:
- update to git v1.8.3.
- expanded set of default filters to include markdown, restructuredtext, and
  man pages.
- better sample configuration file in man page.
- "readme" may now be specified multiple times, and cgit will choose the first
  one it finds.
- "readme" no longer needs a branch name. If prefixed with simply ":" it will
  use the default branch.
- "branch-sort" allowing branches to be sorted either by "age" or "name", for
  kernel.org.
- "enable-index-owner" allowing the owner column to be disabled in the index
  page.
- print submodule revision next to submodule link.
- integrate more closely with git apis, such as strbuf.
- rely on git test harness and git makefiles.
- more robust test suite.
- more rebust makefile dependency accounting.
- pager navigation is now unordered list.
- span tag wraps commit directions.

Behavior changes:
- HOME is no longer passed as an environment variable to any filter api
  scripts.
- "about-filter" now receives the filename being filtered as argv[1]. This may
  disrupt existing scripts, so adjust accordingly.
- gitconfig and gitattributes are no longer loaded from any system directories
  or home directories.

Security:
- CVE-2013-2117: disallow directory traversal when readme is set to filesystem
  path.

Bug fixes:
- ssdiff now correctly manages tab expansion.
- support unannotated tags in http git clone.
- lots of cleanups of global variables and memory leaks.
- do not rely on gettext/libintl.
- better C standard compliance.
- make several functions and variables static.
- improved constification.
- remove unused functions.
- fix colspan values to correct width.
- fix out-of-bounds memory accesses with virtual_root="".
- cache repo config more precisely.
- die when write fails.
