Jun Wu be51116cf4 util: add util.signal that works for non-main threads 
Summary:
The idea is to extend D22703916 (61712e381c)'s way of calling functions from just edenapi to
the entire command for better Ctrl+C handling. Some code paths (ex. pager,
crecord) use `signal.signal` and `signal.signal` does not work from non-main
thread.

To workaround the `signal.signal` limitation, we pre-register all signals we care
about in the main thread to a special handler. The special handler reads a
global variable to decide what to do. Other threads can modify that global
variable to affect what the special signal handler does, therefore indirectly
"register" their handles.

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install::

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing::

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.
