0e121a2cd4 gitweb: Use config file for repository description and URLs
Allow to use configuration variable gitweb.description for repository
description if there is no $GIT_DIR/description file, and multivalued
configuration variable gitweb.url for URLs of a project (to clone or
fetch from) if there is no $GIT_DIR/cloneurl file.

While repository description is shown in the projects list page, so it
is better to use file and not config variable for performance, it is I
think better to use gitweb.url for URLs (as it is shown only on
project summary page).

b201927ac8 gitweb: Read repo config using 'git config -z -l'
Change git_get_project_config to run git-config only once per
repository, without changing its signature (its calling convention).
This means for example that it returns 'true' or 'false' when called
with second argument '--bool', and not true or false value.

Instead of calling 'git config [<type>] --get gitweb.<key>' once for
each config variable, call 'git config -z -l' only once, parsing and
saving its output to %config variable.  This makes possible to add new
per repository configuration without paying cost of forking once per
variable checked.  We can now allow repository description and
repository URLs to be stored in config file without badly affecting
gitweb performance.

For now only configuration variables for 'gitweb' section are stored.

Multiple values for single configuration variable are stored as
anonymous array reference; configuration variable with no value is
stored as undef.

Converting configuration variable values to boolean or integer value
are done in Perl.  Results differ from git-config in the fact that no
conversion error is ever raised.  For boolean values no value, 'true'
(any case) and 'false' (any case) are considered true, numbers are
true if not zero; all other values (even invalid for bool) are
considered false.  For integer values value suffix of 'k', 'm', or 'g'
following decimal number will cause the value to be multiplied by
1024, 1048576, or 1073741824; other values are returned as-is, only
whitespace stripped.

459fa6d0fe git-diff: complain about >=8 consecutive spaces in initial indent
This introduces a new whitespace error type, "indent-with-non-tab".
The error is about starting a line with 8 or more SP, instead of
indenting it with a HT.

This is not enabled by default, as some projects employ an
indenting policy to use only SPs and no HTs.

The kernel folks and git contributors may want to enable this
detection with:

	[core]
		whitespace = indent-with-non-tab

a9cc857ada War on whitespace: first, a bit of retreat.
This introduces core.whitespace configuration variable that lets
you specify the definition of "whitespace error".

Currently there are two kinds of whitespace errors defined:

 * trailing-space: trailing whitespaces at the end of the line.

 * space-before-tab: a SP appears immediately before HT in the
   indent part of the line.

You can specify the desired types of errors to be detected by
listing their names (unique abbreviations are accepted)
separated by comma.  By default, these two errors are always
detected, as that is the traditional behaviour.  You can disable
detection of a particular type of error by prefixing a '-' in
front of the name of the error, like this:

	[core]
		whitespace = -trailing-space

This patch teaches the code to output colored diff with
DIFF_WHITESPACE color to highlight the detected whitespace
errors to honor the new configuration.

c65b670e85 git-p4: Detect changes to executable bit and include them in p4 submit.
This changeset takes advantage of the new parseDiffTreeEntry(...) function to
detect changes to the execute bit in the git repository.  During submit, git-p4
now looks for changes to the executable bit and if it finds them it "reopens"
the file in perforce, which allows it to change the file type.

The logic for adding the executable bit in perforce is straightforward: the +x
modifier can be used. Removing the executable bit in perforce requires that the
entire filetype be redefined (there is no way to join remove the bit with a -x
modifier, for example). This changeset includes logic to remove the executable
bit from the full file type while preserving the base file type and other
modifiers.

4d00bda2aa make the pack index version configurable
It is a good idea to use pack index version 2 all the time since it has
proper protection against propagation of certain pack corruptions when
repacking which is not possible with index version 1, as demonstrated
in test t5302.

Hence this config option.

The default is still pack index version 1.

1cad283a71 gitweb: Easier adding/changing parameters to current URL
Add boolean option '-replay' to href() subroutine, which is used to
generate links in gitweb.  This option "replays" current URL,
overriding it with provided parameters.  It means that current value
of each CGI parameter is used unless otherwise provided.

This change is meant to make it easier to generate links which differ
from current page URL only by one parameter, for example the same view
but sorted by different column:
  href(-replay=>1, order=>"age")
or view which differs by some option, e.g. in log views
  href(-replay=>1, extra_options=>"--no-merges")
or alternate view of the same object, e.g. in the 'blob' view
  href(-replay=>1, action=>"blob_plain")

Actual use of this functionality is left for later.

Always set 'from_file' and 'to_file' keys when parsing raw diff output
format line, even if filename didn't change (file was not renamed).
This allows for simpler code.

Previously, you would have written:

  $diffinfo->{'from_file'} || $diffinfo->{'file'}

but now you can just use

  $diffinfo->{'from_file'}

as 'from_file' is always defined.

While at it, replace (for merge commits)

  $diffinfo->{'from_file'}[$i] || $diffinfo->{'to_file'}

by

  defined $diffinfo->{'from_file'}[$i] ?
          $diffinfo->{'from_file'}[$i] :
          $diffinfo->{'to_file'};

to have no problems with file named '0'.

81f6654a47 Show total transferred as part of throughput progress
Right now it is infeasible to offer to the user a reasonable concept
of when a clone will be complete as we aren't able to come up with
the final pack size until after we have actually transferred the
entire thing to the client.  However in many cases users can work
with a rough rule-of-thumb; for example it is somewhat well known
that git.git is about 16 MiB today and that linux-2.6.git is over
120 MiB.

We now show the total amount of data we have transferred over
the network as part of the throughput meter, organizing it in
"human friendly" terms like `ls -h` would do.  Users can glance at
this, see that the total transferred size is about 3 MiB, see the
throughput of X KiB/sec, and determine a reasonable figure of about
when the clone will be complete, assuming they know the rough size
of the source repository or are able to obtain it.

This is also a helpful indicator that there is progress being made
even if we stall on a very large object.  The thoughput meter may
remain relatively constant and the percentage complete and object
count won't be changing, but the total transferred will be increasing
as additional data is received for this object.

  Use the asyncronous function infrastructure in builtin-fetch-pack.c.
  Add infrastructure to run a function asynchronously.
  upload-pack: Use start_command() to run pack-objects in create_pack_file().
  Have start_command() create a pipe to read the stderr of the child.
  Use start_comand() in builtin-fetch-pack.c instead of explicit fork/exec.
  Use run_command() to spawn external diff programs instead of fork/exec.
  Use start_command() to run content filters instead of explicit fork/exec.
  Use start_command() in git_connect() instead of explicit fork/exec.
  Change git_connect() to return a struct child_process instead of a pid_t.

0f49327c97 Revert "rebase: allow starting from a dirty tree."
This reverts commit 6c9ad166db.
Allowing rebase to start in a dirty tree might have been a worthy
goal, but it is not necessarily always wanted (some people prefer
to be reminded that the state is dirty, and think about the next
action that may not be to stash and proceed).  Furthermore, depending
on the nature of local changes, unstashing the dirty state on top of
the rebased result is not always desirable.

452b800582 Merge branch 'sp/help'
* sp/help:
  shell should call the new setup_path() to setup $PATH
  include $PATH in generating list of commands for "help -a"
  use only the $PATH for exec'ing git commands
  list_commands(): simplify code by using chdir()
  "current_exec_path" is a misleading name, use "argv_exec_path"
  remove unused/unneeded "pattern" argument of list_commands
  "git" returns 1; "git help" and "git help -a" return 0
