Because snapshots can be large, you can save some bandwidth by
supporting caching via If-Modified-Since. This patch adds support for
the i-m-s request to git_snapshot() if the request is a commit.
Requests for snapshots of trees, which lack well defined timestamps,
are still handled as they were before.

The current gitweb only generates Last-Modified and handles
If-Modified-Since headers for the git_feed action. This patch breaks
the Last-Modified and If-Modified-Since handling code out from
git_feed into a new function exit_if_unmodified_since. This makes the
code easy to reuse for other actions.
Only gitweb actions which can easily calculate a modification time
should use exit_if_unmodified_since, as the goal is to balance local
processing time vs. upload bandwidth.

When using regexp search ('sr' parameter / $search_use_regexp variable
is true), check first that regexp is valid.
Without this patch we would get an error from Perl during search (if
searching is performed by gitweb), or highlighting matches substring
(if applicable), if user provided invalid regexp... which means broken
HTML, with error page (including HTTP headers) generated after gitweb
already produced some output.
Add test that illustrates such error: for example for regexp "*\.git"
we would get the following error:
Quantifier follows nothing in regex; marked by <-- HERE in m/* <-- HERE \.git/
at /var/www/cgi-bin/gitweb.cgi line 3084.

Because '--immediate' stops test suite after first error, therefore in
this mode
test_debug 'cat gitweb.log'
was never ran, thus in effect negating effect of '--debug' option.
This made finidng the cause of errors in gitweb test sute difficult.
Modify the gitweb_run test subroutine to run test_debug itself in the
case of errors (and also remove "test_debug 'cat gitweb.log'" from
gitweb tests).
This makes it possible to run *gitweb tests* with --immediate ---debug
combination of options; also it makes gitweb tests to not output
spurious debug data that is not considered error.

The first (setup) test attempts to create a file, using the
test_commit function, called 'i can has snapshot?'. On cygwin
(and MinGW) this fails with a "No such file or directory" error.
In order to fix the tests, we simply remove the '?' wildcard
from the name, since the purpose of these tests is not about
creating funny filenames.

Several tests did not use test_expect_success for their setup
commands. Putting these start commands into the testing framework
means both that errors during setup will be caught quickly and that
non-error text will be suppressed without -v.

Revert the previous attempt to skip this test on platforms where we
currently cannot determine the system load. We want to make sure that
the max-load-limit codepath produces results cleanly, when gitweb is
updated and becomes capable of reading the load average by some other
method.
The code to check for load returns 0 if it doesn't know how to find
load. It also checks to see if the current load is higher than the
max load. So to force the script to quit early by setting the maxload
variable negative which should work for systems where we can detect
load (which should be a positive number) and systems where we can't
(where detected load is 0)

Currently gitweb only knows how to check for load using /proc/loadavg,
which isn't available on all systems. We shouldn't fail the test just
because we don't know how to check the system load.

This changes slightly the behavior of gitweb, so that it verifies
that the box isn't inundated with before attempting to serve gitweb.
If the box is overloaded, it basically returns a 503 Server Unavailable
until the load falls below the defined threshold. This helps dramatically
if you have a box that's I/O bound, reaches a certain load and you
don't want gitweb, the I/O hog that it is, increasing the pain the
server is already undergoing.
This behavior is controlled by $maxload configuration variable.
Default is a load of 300, which for most cases should never be hit.
Unset it (set it to undefined value, i.e. undef) to turn off checking.
Currently it requires that '/proc/loadavg' file exists, otherwise the
load check is bypassed (load is taken to be 0). So platforms that do
not implement '/proc/loadavg' currently cannot use this feature
(provisions are included for additional checks to be added by others).
There is simple test in t/t9501-gitweb-standalone-http-status.sh to
check that it correctly returns "503 Service Unavailable" if load is
too high, and also if there are any Perl warnings or errors.

Remove test_debug lines after 'snapshots: tgz only default format
enabled' and 'snapshots: all enabled in default, use default disabled
value' tests. Those tests constitute of multiple gitweb_run
invocation, therefore outputting gitweb.output for the last gitweb_run
wouldn't help much in debugging test failure, and can only confuse.
For snapshot tests which check for "200 OK" status, change
test_debug 'cat gitweb.output'
to
test_debug 'cat gitweb.headers'
Otherwise when running this test with '--debug' option,
t/t9501-gitweb-standalone-http-status.sh would dump *binary data* (the
snapshot itself) to standard output, which can mess up state of terminal
due to term control characters which can be embedded in output.

* mr/gitweb-snapshot:
t/gitweb-lib: Split HTTP response with non-GNU sed
gitweb: Smarter snapshot names
gitweb: Document current snapshot rules via new tests
t/gitweb-lib.sh: Split gitweb output into headers and body
gitweb: check given hash before trying to create snapshot
Makes things nicer in cases when you hand craft the snapshot URL but
make a typo in defining the hash variable (e.g. netx instead of next);
you will now get an error message instead of a broken tarball.
Tests for t9501 are included to demonstrate added functionality.
