sslutil: try harder to avoid getpeercert problems
We wrap both calls to getpeercert in a try/except to make sure we
catch its bogus AttributeError.
copies._forwardcopies: use set operations to find missing files
This is a performance win for a number of reasons:
- We don't iterate over contexts, which avoids a completely unnecessary sorted
call + the O(number of files) abstraction cost of doing that.
- We don't check membership in a context, which avoids another
O(number of files) abstraction cost.
- We iterate over the manifests in C instead of Python.
For a large repo with 170,000 files, this improves perfpathcopies from 0.34
seconds to 0.07. Anything that uses pathcopies, such as rebase or diff --git
between two revisions, benefits.
perf: add a command to test copies.pathcopies perf
An upcoming patch will improve the performance of this function, and this
command will be used to demonstrate that improvement.

applyupdates: assign variable before we try to use it (
issue3855)
The variable 'fd' was getting used with a value left over from a prior
iteration, causing a KeyError: '.hgsubstate'.
