git-svn: fix dcommit clobbering when committing a series of diffs
Our revision number sent to SVN is set to the last revision we
committed if we've made any previous commits in a dcommit
invocation.
Although our SVN Editor code uses the delta of two (old) trees
to generate information to send upstream, it'll still send
complete resultant files upstream; even if the tree they're
based against is out-of-date.
The combination of sending a file that does not include the
latest changes, but set with a revision number of a commit we
just made will cause SVN to accept the resultant file even if it
was generated against an old tree.
More trouble was caused when fixing this because we were
rebasing uncessarily at times. We used git-diff-tree to check
the imported SVN revision against our HEAD, not the last tree we
committed to SVN. The unnecessary rebasing caused merge commits
upstream to SVN to fail.

git-reset: do not be confused if there is nothing to reset
The purpose of the function update_index_from_diff() (which is the
callback function we give do_diff_cache()) is to update those index
entries which differ from the given commit.
Since do_diff_cache() plays games with the in-memory index, this function
discarded the cache and reread it.
Then, back in the function read_from_tree() we wrote the index.
Of course, this broke down when there were no changes and
update_index_from_diff() was not called, and therefore the mangled index
was not discarded.
The solution is to move the index writing into the function
update_index_from_diff().

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

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

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.
