phabricator: add a small language to query Differential Revisions

Previously, `phabread` can only be used to read a single patch, or a single
stack of patches. In the future, we want to have more complex queries like
filtering with status (open, accepted, closed, etc), or maybe more complex
like filtering by reviewers etc. The command line flag approach won't scale
with that.

Besides, we might want to have other commands to update Differential
Revision status in batch, like accepting a stack using a single command.

Therefore, this patch adds a small language. It has basic set operations:
`&`, `+`, `-` and an ancestor operator to support `--stack`.

Test Plan:
Try querying this Phabricator instance:

  hg phabread 1+2 # 1, 2
  hg phabread D2+D1 # 2, 1
  hg phabread ':118-115+:2-1' # 114, 116, 117, 118, 2
  hg phabread '((:118-(D115+117)))&:117' # 114, 116
  hg phabread ':2&:117' --debug # differential.query is called only once

Make sure the output is expected and prefetch works.

Put here definitions of blacklists for run-tests.py

Create a file per blacklist. Each file should list the names of tests that you
want to be skipped.
File names are meant to be used as targets for run-tests.py --blacklist
option.
Lines starting with # are ignored. White spaces are stripped.

e.g. if you create a blacklist/example file containing:
 test-hgrc
 # some comment
 test-help
then calling "run-tests.py --blacklist blacklists/example" will exclude
test-hgrc and test-help from the list of tests to run.
