test: split test-largefile.t in multiple file

The `test-largefiles.t` unified test is significantly longer (about 30%) than
any other tests in the mercurial test suite. As a result, its is alway the last
test my test runner is waiting for at the end of a run.

In practice, this means that `test-largefile.t` is wasting half a minute of my
life every times I'm running the mercurial test suites. This probably mean more
a few cumulated day by now.

I've finally decided to split it up in multiple smaller tests to bring it back in
reasonable length.

This changeset extracts independent test cases in two files. One dedicated to
wire protocole testing, and another one dedicated to all other tests that could
be independently extracted.

No test case were haltered in the making of this changeset.

Various timing available below. All timing have been done on a with 90 jobs on a
64 cores machine. Similar result are shown on firefly (20 jobs on 12 core).

General timing of the whole run
--------------------------------

We see a 25% real time improvement for no significant cpu time impact.

Before split:

    real   2m1.149s
    user  58m4.662s
    sys   11m28.563s

After split:

    real   1m31.977s
    user  57m45.993s
    sys   11m33.634s


Last test to finish (using run-test.py --time)
----------------------------------------------

test-largefile.t is now finishing at the same time than other slow tests.

Before split:

    Time      Test
    119.280   test-largefiles.t
     93.995   test-mq.t
     89.897   test-subrepo.t
     86.920   test-glog.t
     85.508   test-rename-merge2.t
     83.594   test-revset.t
     79.824   test-keyword.t
     78.077   test-mq-header-date.t

After split:

    Time      Test
    90.414   test-mq.t
    88.594   test-largefiles.t
    85.363   test-subrepo.t
    81.059   test-glog.t
    78.927   test-rename-merge2.t
    78.021   test-revset.t
    77.777   test-command-template.t



Timing of largefile test themself
-----------------------------------

Running only tests prefixed with "test-largefiles".
No significant change in cumulated time.

Before:

    Time     Test
    58.673   test-largefiles.t
     2.931   test-largefiles-cache.t
     0.583   test-largefiles-small-disk.t

After:

    Time     Test
    31.754   test-largefiles.t
    17.460   test-largefiles-misc.t
     8.888   test-largefiles-wireproto.t
     2.864   test-largefiles-cache.t
     0.580   test-largefiles-small-disk.t

# bash completion for the Mercurial distributed SCM -*- sh -*-

# Docs:
#
# If you source this file from your .bashrc, bash should be able to
# complete a command line that uses hg with all the available commands
# and options and sometimes even arguments.
#
# Mercurial allows you to define additional commands through extensions.
# Bash should be able to automatically figure out the name of these new
# commands and their options.  See below for how to define _hg_opt_foo
# and _hg_cmd_foo functions to fine-tune the completion for option and
# non-option arguments, respectively.
#
#
# Notes about completion for specific commands:
#
# - the completion function for the email command from the patchbomb
#   extension will try to call _hg_emails to get a list of e-mail
#   addresses.  It's up to the user to define this function.  For
#   example, put the addresses of the lists that you usually patchbomb
#   in ~/.patchbomb-to and the addresses that you usually use to send
#   the patchbombs in ~/.patchbomb-from and use something like this:
#
#      _hg_emails()
#      {
#          if [ -r ~/.patchbomb-$1 ]; then
#              cat ~/.patchbomb-$1
#          fi
#      }
#
#
# Writing completion functions for additional commands:
#
# If it exists, the function _hg_cmd_foo will be called without
# arguments to generate the completion candidates for the hg command
# "foo".  If the command receives some arguments that aren't options
# even though they start with a "-", you can define a function called
# _hg_opt_foo to generate the completion candidates.  If _hg_opt_foo
# doesn't return 0, regular completion for options is attempted.
#
# In addition to the regular completion variables provided by bash,
# the following variables are also set:
# - $hg - the hg program being used (e.g. /usr/bin/hg)
# - $cmd - the name of the hg command being completed
# - $cmd_index - the index of $cmd in $COMP_WORDS
# - $cur - the current argument being completed
# - $prev - the argument before $cur
# - $global_args - "|"-separated list of global options that accept
#                  an argument (e.g. '--cwd|-R|--repository')
# - $canonical - 1 if we canonicalized $cmd before calling the function
#                0 otherwise
#
