directaccess: disable directaccess for push and serve
Before this patch, push and serve were subject to directaccess. This patch
makes them throw error when trying to access hidden hashes.

directaccess: change rule from opt-in to opt-out
Before this patch we would opt-in commands for direct access and the default
filter for new repository was 'visible'.
With this patch, the default filter for new repos is
'visible-directaccess-warn'. It means that by default all the commands have
directaccess with warnings.

inhibit: move transaction wrapping outside of repo setup
Before this patch, transaction wrapping code was done in reposetup. It happened
to cause stackoverflows in repos with a lot of subreps.
This patch moves the wrapping to extsetup and avoids this problem.

tests: ignores other core output in capability testing
This will avoid breaking the test anytime core changes.

evolve: make uncommit respect allowunsable
Before this patch, the uncommit command was performing the same way regardless
of the value of experimental.evolution.
With this patch if the configuration does not allow unstability, uncommit won't
create instability.

directaccess: use cached filteredrevs
Before this patch we were calling directly repoview.computehidden(repo) to
compute the revisions visible with direct access, without going through the
caching mechanism for the filtered revisions.
There was two issues with that:
(1) Performance: We were not leverating the cached values of the 'visible' revs
(2) Stability: If there were to be a cache inconsistency with the computation of
'visible' we would crash in the branchmap consistency check partial.validfor.
Consider the scenario of rebase with bookmarks:
- when we delete a bookmark on an obsolete changeset (like what rebase
does when moving the bookmark after rebasing the changesets)
- then this changes the value returned by repoview.computehidden(repo) as
bookmarks are used as dynamic blockers in repoview.computehidden(repo)
- as of now, we don't invalidate the cache in the case of bookmark change
- if we have a cached value from before the bookmark change,
repoview.filterrevs(repo, 'visible') considers the cached value correct and
returns something different than repoview.computehidden(repo)
- in turn, if we use repoview.computehidden(repo) in directaccess, the subset
relationship is broken and the cache consistency assertion (parial.validfor)
fails if branchmap.updatecache is called in this time window
This patch leverages the caching infrastructure in place to speed up the
computation of the filteredrevs for visible-directaccess-nowarn and
visible-directaccess-warn. Incidentally it prevents the bug discussed in (2)
from crashing when running a rebase with a bookmark. Note that there still
needs to be a fix in core for the case discussed in (2).
The test for this side of the fix (not core's fix for (2) is very hard to
implement without introducing a lot of dependencies and does not belong
here. It is much easier to have the test of the fix for the scenario (2) in
core along with the fix.

inhibit: improve performance of transaction wrapping
Before this patch, transaction wrapping was the most expensive part of inhibit
computation wise. This patch changes the revset that we use in the transaction
wrapping to make it ~50x faster to compute:
revset #0: obsolete() - hidden()
0) wall 0.000214 comb 0.000000 user 0.000000 sys 0.000000 (best of 11209)
vs
revset #0: (not hidden()) and obsolete()
0) wall 0.010965 comb 0.010000 user 0.010000 sys 0.000000 (best of 237)

evolve: extract the code computing dependencies in a separate function
The code to compute dependencies between unstable changeset can be reused to
compute the next reveset. This patch extracts it in its own function to make
it reusable.

directaccess: add mechanism to load directaccess after some other extensions
directaccess needs to load after some extensions to avoid interfering with them.
This patch adds a mechanism to specify what extension directaccess needs to load
after.
Laurent Charignon <lcharignon@fb.com> [Tue, 02 Jun 2015 15:24:12 -0700] rev 1359
evolve: add another test for evolve --rev
This patch adds one test for three conditions not covered before:
- evolve --rev on a stack with obsolete commits without successors
- evolve --rev on two sets of stacks in parallel
- evolve --rev on a set of stack partially solvable (because all of the
commits of the stack are not specified with --rev)
