revset: delete _updatedefaultdest as it has no users
The revset is not used anywhere anymore. We delete the function until we use
(and therefore test it again).

merge: get the default update destination from the function
There is no value in using the revset instead of the extracted function.

update: move default destination computation to a function
We ultimately want this to be accessible through a revset, but there is too
much complexity here for that to work. Especially we'll have to return more
than just the destination to control the behavior (eg: bookmarks to activate,
etc).
To prevent cycle, a new module is created, it will receive other
destination/behavior function in the future.

worker: restore old countcpus code (issue4869)
This is a backout of d29859cfcfc2. The stdlib implementation of
multiprocessing.cpu_count() attempts to invoke a process on BSD and
Darwin platforms (at least on 2.7). Under certain conditions (such as
cwd being removed) this could raise. Our old code was silently catching
the exception.
The old code was more robust, so restore it.

filemerge: call premerge directly from main merge function
The merge code currently does (in pseudocode):
for f in tomerge:
premerge f
merge f
We'd like to change this to look more like:
for f in tomerge:
premerge f
for f in tomerge:
merge f
This makes sure as many files are resolved as possible before prompting for the
others. This restructuring is also necessary for custom merge drivers.
This function separates out the premerge step from the merge step. In future
patches we'll actually turn these into separate steps in the merge driver.
The 'if r:' occurrences will be cleaned up in subsequent patches.

bundle2: allow lazily acquiring the lock
In the external pushrebase extension, it is valuable to be able to do some work
without taking the lock (like running expensive hooks). This enables
significantly higher commit throughput.
This patch adds an option to lazily acquire the lock. It means that all bundle2
part handlers that require writing to the repo must first call
op.gettransction(), when in this mode.

bundle2: add op.gettransaction() to handlers that need the lock
A future patch will allow the bundle2 lock be taken lazily. We need to
introduce transaction-gets to each handler that needs the lock.
The tests caught these issues when I added lazy locking.

patchbomb: add a 'bundletype' config under 'patchbomb'
patchbomb relies on the 'hg bundle' command to generate an attached bundle using
--bundle. However, while 'hg bundle' has a --type option, patchbomb did not.
This is becoming very relevant since we are about to issue bundle2 for
general-delta repository.

import: allow processing of extra part header after import
As we have a way for extension to add more header, we need a way for them to
actually process them. We add a basic hook point to do extra work after the
import have been committed.

import: allow processing of extra part header during import
As we have a way for extension to add more header, we need a way for them to
actually process them. We add a basic hook points to alter the changeset
(especially extra) before we commit. There would be more to do for a full
featured hooking, but this currently fit my needs.

patch: move 'extract' return to a dictionnary
The final goal here is to be able to parse, return and process arbitrary data
from patch. This mirror the recently added ability to add arbitrary data to
patch headers.
The first step is to return something more flexible, so we return a dict without
changing any other logic.

patchbomb: add experimental config of a "pullurl" and export it
This config allows to specify a public location where your changeset can be
found. It then include a dedicated patch header show a command to be used to
retrieve the change. See the test for example.
This is flagged as experimental because this feature is not safe until we have
more logic to test that:
- changeset actually exists on destination
- changeset is draft on destination.
As all this is experimental, bike shedding can happily happens before we remove
the experimental flag.

incoming: request a bundle2 when possible (BC)
Incoming was using bundle1 in all cases, as bundle1 is restricted to
changegroup1 and does not support general delta, this can lead to significant
CPU overhead if the server is using general delta storage. We now properly
request and store a bundle2 to disk.
If the server include any output or error in the bundle, they will be stored on
disk and replayed when the bundle is read. As 'hg incoming' is going to read the
bundle right away, we call that 'good' enough and go back to the bigger plan of
having general delta on by default.
