aliases: provide more flexible ways to work with shell alias arguments

This patch changes the functionality of shell aliases to add more powerful
options for working with shell alias arguments.

First: the alias name + arguments to a shell alias are set as an HG_ARGS
environment variable, delimited by spaces. This matches the behavior of hooks.

Second: any occurrences of "$@" (without quotes) are replaced with the
arguments, separated by spaces. This happens *before* the alias gets to the shell.

Third: any positive numeric variables ("$1", "$2", etc) are replaced with the
appropriate argument, indexed from 1. "$0" is replaced with the name of the
alias. Any "extra" numeric variables are replaced with an empty string.  This
happens *before* the alias gets to the shell.

These changes allow for more flexible shell aliases:

    [alias]
    echo = !echo $@
    count = !hg log -r "$@" --template='.' | wc -c | sed -e 's/ //g'
    qqueuemv = !mv "`hg root`/.hg/patches-$1" "`hg root`/.hg/patches-$2"

In action:

    $ hg echo foo
    foo

    $ hg count 'branch(default)'
    901

    $ hg count 'branch(stable) and keyword(fixes)'
    102

    $ hg qqueuemv myfeature somefeature

#!/bin/sh

echo "[extensions]"      >> $HGRCPATH
echo "share = "          >> $HGRCPATH

echo % prepare repo1
hg init repo1
cd repo1
echo a > a
hg commit -A -m'init'

echo % share it
cd ..
hg share repo1 repo2

echo % contents of repo2/.hg
cd repo2
[ -d .hg/store ] \
  && echo "fail: .hg/store should not exist" \
  || echo "pass: .hg/store does not exist"
# Some sed versions appends newline, some don't, and some just fails
(cat .hg/sharedpath; echo) | head -n1 | "$TESTDIR/filtertmp.py"

echo % commit in shared clone
echo a >> a
hg commit -m'change in shared clone'

echo % check original
cd ../repo1
hg log
hg update
cat a             # should be two lines of "a"

echo % commit in original
echo b > b
hg commit -A -m'another file'

echo % check in shared clone
cd ../repo2
hg log
hg update
cat b             # should exist with one "b"

echo % hg serve shared clone
hg serve -n test -p $HGPORT -d --pid-file=hg.pid
cat hg.pid >> $DAEMON_PIDS
