rust: simplify pattern file parsing
Previously we kept the pattern syntax as a &[u8] until the last
possible moment, which meant we had to handle potential errors when
parsing that &[u8]. But such errors could never actually occur, given
the structure of the code.
Now we parse it eagerly (in two places) and pass it around as a
PatternSyntax, so we can delete some error handling code.
parse_one_pattern is in particular useful for parsing patterns passed
on the command line, as we'll support later in this series.
$ hg init t
$ cd t
$ echo import > port
$ hg add port
$ hg commit -m 0 -u spam -d '0 0'
$ echo export >> port
$ hg commit -m 1 -u eggs -d '1 0'
$ echo export > port
$ echo vaportight >> port
$ echo 'import/export' >> port
$ hg commit -m 2 -u spam -d '2 0'
$ echo 'import/export' >> port
$ hg commit -m 3 -u eggs -d '3 0'
$ head -n 3 port > port1
$ mv port1 port
$ hg commit -m 4 -u spam -d '4 0'
pattern error
$ hg grep '**test**'
grep: invalid match pattern: nothing to repeat* (glob)
[1]
invalid revset syntax
$ hg log -r 'diffcontains()'
hg: parse error: diffcontains takes at least 1 argument
[10]
$ hg log -r 'diffcontains(:)'
hg: parse error: diffcontains requires a string pattern
[10]
$ hg log -r 'diffcontains("re:**test**")'
hg: parse error: invalid regular expression: nothing to repeat* (glob)

Moved line may not be collected by "grep --diff" since it first filters
the contents to be diffed by the pattern. (i.e.
"diff <(grep pat a) <(grep pat b)", not "diff a b | grep pat".)
This is much faster than generating full diff per revision.

Grepping a symlink greps its destination
$ rm -f added; ln -s symlink-added added

But we reject symlinks as directories components of a tracked file as
usual:

$ rm -rf dir; ln -s / dir
$ hg grep ''
abort: path 'dir/f' traverses symbolic link 'dir'

--follow with/without --diff and/or paths
-----------------------------------------
For each test case, we compare the history traversal of "hg log",
"hg grep --diff", and "hg grep" (--all-files).
"hg grep --diff" should traverse the log in the same way as "hg log".
"hg grep" (--all-files) is slightly different in that it includes
unmodified changes.
