Summary:
Move the strip extension to core. Rename the command to `hg debugstrip` as it
is not intended for use by users. Users should use `hg hide` instead.

Summary:
We're encountering an issue that I think is caused by invalid data
coming back from memcache, possibly due to our recently introduced connection
reusing. Let's add some checksums to verify that the data we put in is identical
to the data we get out for a given key.

Summary:
Importing anything from python files with explicit breaks embedded
aproach we use on Windows.
For one of the tests, I did add `hg debugshell -c "from hgext import sparse;
print sparse.__file__` just to make sure the same file is used in practice.

Summary:
When you get an error, let's print the number of conflicts in each file. This will give the user some sense of how much work they have to do.
The code change is entirely in `filemerge.py`, and `tests/test-merge-conflict-count.t` adds a new test.

Use common templating, including colors, between sparse show and sparse list.

Summary:
We have our fbsparse, which we are using. We can rename it later when configs
are in the same repo as the extension files.
Test Plan: - run tests, see only the failures related to the other commits in the stack

Previously, [include] was implicit and pattern lines before a
[section] were added to includes.
Because the format may change in the future and explicit behavior,
well, more explicit, this commit changes the config parser to
reject pattern lines that don't occur in a [section].

I'm not sure if the difference on Windows for test-sparse.t is expected or not.
It looks like unless the leading '/' is followed by a drive letter, '/' is
resolved to 'C:/MinGW/msys/1.0'. But both cases abort with "not under root"
instead of just warning.
Sparse checkout is still highly experimental and not protected
by BC guarantees yet. We also haven't had a discussion on the UX.
To discourage use, we rename the sparse command to debugsparse.
Facebook has developed an extension to enable "sparse" checkouts -
a working directory with a subset of files. This feature is a critical
component in enabling repositories to scale to infinite number of
files while retaining reasonable performance. It's worth noting
that sparse checkout is only one possible solution to this problem:
another is virtual filesystems that realize files on first access.
But given that virtual filesystems may not be accessible to all
users, sparse checkout is necessary as a fallback.
Per mailing list discussion at
https://www.mercurial-scm.org/pipermail/mercurial-devel/2017-March/095868.html
we want to add sparse checkout to the Mercurial distribution via
roughly the following mechanism:
1. Vendor extension as-is with minimal modifications (this patch)
2. Refactor extension so it is more clearly experimental and inline
with Mercurial practices
3. Move code from extension into core where possible
4. Drop experimental labeling and/or move feature into core
after sign-off from narrow clone feature owners
This commit essentially copies the sparse extension and tests
from revision 71e0a2aeca92a4078fe1b8c76e32c88ff1929737 of the
https://bitbucket.org/facebook/hg-experimental repository.
A list of modifications made as part of vendoring is as follows:
* "EXPERIMENTAL" added to module docstring
* Imports were changed to match Mercurial style conventions
* "testedwith" value was updated to core Mercurial special value and
comment boilerplate was inserted
* A "clone_sparse" function was renamed to "clonesparse" to appease
the style checker
* Paths to the sparse extension in tests reflect built-in location
* test-sparse-extensions.t was renamed to test-sparse-fsmonitor.t
and references to "simplecache" were removed. The test always skips
because it isn't trivial to run it given the way we currently run
fsmonitor tests
* A double empty line was removed from test-sparse-profiles.t
There are aspects of the added code that are obviously not ideal.
The goal is to make a minimal number of modifications as part of
the vendoring to make it easier to track changes from the original
implementation. Refactoring will occur in subsequent patches.
