hgweb: fix websub regex flag syntax on Python 3
The `websub` config section for hgweb is broken under Python 3
when using regex flags syntax (ie the optional `i` in the example
from `hg help config.websub`:
patternname = s/SEARCH_REGEX/REPLACE_EXPRESSION/[i]
Flags are pulled out of the specified byte-string using a regular
expression, and uppercased. The flags are then iterated over and
passed to the `re` module using `re.__dict__[item]`, to get the
object attribute of the same name from the `re` module. So on Python
2 if the `il` flags are passed, this transition looks like:
`'il'` -> `'IL'` -> `'I'` -> `re.__dict__['I']` -> `re.I`
However on Python 3, these are bytes objects. When we iterate over
a bytes object in Python 3, instead of getting the individual characters
in the string as string objects of length one, we get the integer \
value corresponding to that byte. So the same transition looks like:
`b'il'` -> `b'IL'` -> `73` -> `re.__dict__[73]` -> `KeyError`
This commit fixes the type mismatch by converting the bytes to a
system string before iterating over each element to pass to `re`.
The transition will now look like:
`b'il'` -> `u'IL'` -> `u'I'` -> `re.__dict__[u'I']` -> `re.I`
In addition we expand `test-websub.t` to cover the regex flag case
(for both the `websub` section and `interhg`).

phabricator: don't abort if property writing fails during amending
Currently if one of the writediffproperty calls fails due to network issues
during the amending of commit messages to include the Diff. Rev. line, the
transaction is aborted and rolled back. This means that the associations
between the commits and the DREVs are lost for any already amended commits
because the removal of the local tags isn't covered by the rollback.

relnotes: we now require `sh` to support $(command) syntax to run test suite
For example, Solaris before version 11 had /bin/sh pointing to the old
Bourne Shell (which doesn't support $(command) syntax).

merge: respect parents order when using `graft` on a merge
The previous code did not record the index of the replaced parent. It was always
using the "graft" destination as `p1`. This could switch parents order in some
situation (eg: some of the evolve evolving merge case). Recording and using the
information fixes the issue in evolve.
We are not aware of core commands calling graft in that fashion, so we could not
build a simple test case for it using core commands.
