Similar in spirit to 07cf0f24 (make --max-pack-size argument to 'git
pack-object' count in bytes, 2010-02-03) which made the option by the same
name to pack-objects, this counts the pack size limit in bytes.

In order not to cause havoc with people used to the previous megabyte
scale an integer smaller than 8192 is interpreted in megabytes but the
user gets a warning.  Also a minimum size of 1 MiB is enforced to avoid an
explosion of pack files.

Currently, when called without -n and -f, git clean issues

fatal: clean.requireForce not set and -n or -f not given; refusing to clean

which leaves the user wondering why force is required when requireForce
is not set. Looking up in git-clean(1) does not help because its
description is wrong.

Change it so that git clean issues

fatal: clean.requireForce defaults to true and -n or -f not given; refusing to clean

The value passed to --max-pack-size used to count in MiB which was
inconsistent with the corresponding configuration variable as well as
other command arguments which are defined to count in bytes with an
optional unit suffix.  This brings --max-pack-size in line with the
rest of Git.

Also, in order not to cause havoc with people used to the previous
megabyte scale, and because this is a sane thing to do anyway, a
minimum size of 1 MiB is enforced to avoid an explosion of pack files.

Current handling of pack_size_limit is quite suboptimal.  Let's consider
a list of objects to pack which contain alternatively big and small
objects (which pretty matches reality when big blobs are interlaced
with tree objects).  Currently, the code simply close the pack and opens
a new one when the next object in line breaks the size limit.

The current code may degenerate into:

  - small tree object => store into pack #1
  - big blob object busting the pack size limit => store into pack #2
  - small blob but pack #2 is over the limit already => pack #3
  - big blob busting the size limit => pack #4
  - small tree but pack #4 is over the limit => pack #5
  - big blob => pack #6
  - small tree => pack #7
  - ... and so on.

The reality is that the content of packs 1, 3, 5 and 7 could well be
stored more efficiently (and delta compressed) together in pack #1 if
the big blobs were not forcing an immediate transition to a new pack.

Incidentally this can be fixed pretty easily by simply skipping over
those objects that are too big to fit in the current pack while trying
the whole list of unwritten objects, and then that list considered from
the beginning again when a new pack is opened.  This creates much fewer
smallish pack files and help making more predictable test cases for the
test suite.

This change made one of the self sanity checks useless so it is removed
as well. That check was rather redundant already anyway.

First of all, trying to run 'git verify-pack' on packs  produced by
the tests using pack.packSizeLimit always failed.  After lots of digging
and head scratching, it turns out that the preceeding test simulating
a SHA1 collision did leave the repository quite confused, impacting
subsequent tests.

So let's move that destructive test last, and add tests to run
verify-pack on the output from those packSizeLimit tests to catch such
goofage.

Finally, group those packSizeLimit tests together.

The chop_str subroutine is meant to be used on strings (such as commit
description / title) *before* HTML escaping, which means before
applying esc_html or equivalent.

Therefore get rid of the failed attempt to always remove full HTML
entities (like e.g. & or  ).  It is not necessary (HTML
entities gets added later), and it can cause chop_str to chop a string
incorrectly.

enable configure to set NO_$PROGRAM in addition to an empty

disable the use of python, as the remote helper code has nothing
leveraging it yet.

If one of $site_header, $site_footer or $home_text is not defined, you

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

invocation, therefore outputting gitweb.output for the last gitweb_run

For snapshot tests which check for "200 OK" status, change

  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
