run-tests: move t test parsing into its own function
Test parsing is somewhat complicated. This patch extracts it into its
own function.
The impetus of this patch is folding tsttest() into the TTest class.
Subsequent patches will continue this work until tsttest() no longer
exists.
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.
