python3: add raw prefix to all array.array() calls

python3: add raw prefix to "troubles"-related dicts The `byteify-strings.py` script cannot know that these will be used in a way that requires to use a system string without some pretty hardcore hardcoding.

python3: add raw prefix in cases harder to analyze at the token level The `byteify-strings.py` script would be a lot more complicated if it had to do backtracking and other more advanced static analysis to figure our those cases, so we have to add the raw prefix to those cases manually.

python3: add byte prefix for objects that look like kwargs but aren't The `byteify-strings.py` script has no way of knowing that those aren't acutally kwargs since it works purely at the tokenization level, so we have to add the byte prefix to their keys manually.

python3: mark all SQL queries as raw strings

python3: prefix all regex to work with python 2 and 3

pick: added support for hg abort This patch isolates abort logic for `hg pick --abort` as `abortpick()`. For independent calls via `hg abort` `hgabortpick()` is created and registered to the state detection API. Results are shown as tests.

pick: factor our the abort function This prepare the upcoming support for `hg pick` in `hg abort.

abort: added support for evolve to hg abort This patch adds support of `hg evolve --abort` to `hg abort` plan. This involves creating a `hgabortevolve()` function under `evolvecmd` which ensures abortion of evolve via `hg abort`. This function is then registered using `addunfinished()` in `__init__.py`. Results are shown as tests.

evolve: fixed lock acquire before checking state Before checking the states `repo.lock()` and `repo.wlock()` need to be acquired. This was not happening in `evolve()` earlier. This patch creates a seperate `_performevolve()` funtion which can be then called with locks acquired. This also removes the redundant lock acuquiring of `abortevolve` and `continueevolve` as lock is now taken earlier.
