test: further fixes to matching for run-tests.py bug The fix in bac24a8a095a did not fix the full issue, because the extra number also eat some of the separator space. Since we are already matching arbitrary number of space, we easily fix the matching.

branchmap: explicitly warm+write all subsets of the branchmap caches 'full' claims it will warm all of the caches that are known about, but this was not the case - it did not actually warm the branchmap caches for subsets that we haven't requested, or for subsets that are still considered "valid". By explicitly writing them to disk, we can force the subsets for ex: "served" to be written ("immutable" and "base"), making it cheaper to calculate "served" the next time it needs to be updated.

changectx: extract explicit computechangesetfilesremoved method from context Right now, the logic around changeset centric removed files data are buried into the "changectx" code. We extract this code in a dedicated method (in the scmutil module) for clarity. This clarity will help to explicitly compute and caches these data in the future.

changectx: extract explicit computechangesetfilesadded method from context Right now, the logic around changeset centric added files data are buried into the "changectx" code. We extract this code in a dedicated method (in the scmutil module) for clarity. This clarity will help to explicitly compute and caches these data in the future.

demandimport: explicitly declare `_session` at the module level The `_session` module level variable is set within a function using the `global` keyword. This confuses my `test-check-pyflakes.t`. Explicitly declaring the variable at the top level solves the issue (and seems absolutely reasonable).

tests: give more room for slowness in test-run-tests.t The test expected any run-test.py run to end in less than 10 seconds. On slower loaded CI machine, this gets slower than that. We give a bit more room to the regexp.

copies: extract an explicit `computechangesetcopie` method from context Right now, the logic around changeset centric copies data are buried into the "changectx" code. We extract this code in a dedicated method (in the copies module) for clarity. This clarity will help to explicitly compute and caches these data in the future.

config: fix fm.data() handling of defaultvalue This is a follow-up patch to rHG51a2e3102db2. This moves `fm.data()` out of the if block in `commands.config()`. Differential Revision: https://phab.mercurial-scm.org/D6720

config: remove pycompat.bytestr() for defaultvalue This is a follow-up patch to 51a2e3102db2. This removes `pycompat.bytestr` to preserve `None` in `commands.config()`. Differential Revision: https://phab.mercurial-scm.org/D6712

unshelve: clear shelvedstate and _finishunshelve() on partial unshelve On a partial unshelve, `shelvedstate` was not cleared and `_finishunshelve()` was not called. Ideally, these should be called on this case. This patch makes `shelvedstate` to delete after a successful partial unshelve and calls `_finishunshelve()` in the same case.
