This patch adds a new vcs-version file that is generated via git (and
can be adapted if VCS is changed) and then embebbded as VCS_VERSION in
the constants module.

This means two things:
- local modifications without committing to git (or when using a tar.gz
  archive + mods) will not be reflected
- version is fixed at the time of the last make regen-vcs-version (dist time,
  or devel/upload which calls this)

Thus this is more geared at developers rather than end users.

The patch:

- adds rules for generating the vcs-version file
- adds a dist-hook for re-generating the file (if possible) and copying
  the updated version to the distdir
- modifies devel/upload to re-generate the file before upload

The output of --version will look like:
gnt-cluster (ganeti v2.2.0beta0-184-gebca7e6) 2.2.0~beta0

Instead of using our custom HTTP client, using PycURL's multi
interface allows us to get rid of the HTTP client threadpool.
The majority of the code is still in the ganeti.http.client
module.

A simple per-thread HTTP client pool gives cURL a chance to
cache and retain as much information as possible (e.g. SSL certs).
Unused HTTP clients (e.g. due to removed nodes) are deleted after
25 requests going through the pool.

This patch adds lock names to SharedLocks and LockSets, that can be used
later for displaying the actual locks being held/used in places where we
only have the lock, and not the entire context of the locking operation.

Since I realized that the production code doesn't call LockSet with the
proper members= syntax, but directly as positional parameters, I've
converted this (and the arguments to GlobalLockManager) into positional
arguments.

Since migration live/non-live is more stable (e.g.) for Xen-PVM versus
Xen-HVM, we introduce a new parameter for what mode we should use by
default (if not overridden by the user, in the opcode).

The meaning of the opcode 'live' field changes from boolean to either
None (use the hypervisor default), or one of the allowed migration
string constants. The live parameter of the TLMigrateInstance is still a
boolean, computed from the opcode field (which is no longer passed to
the TL).

By splitting the _WaitForJobChangesHelper class into multiple smaller
classes, we gain in several places:

- Simpler code, less interaction between functions and variables
- Easy to unittest (close to 100% coverage)
- Waiting for job changes has no direct knowledge of queue anymore (it
  doesn't references queue functions anymore, especially not private ones)
- Activate inotify only if there was no change at the beginning (and
  checking again right away to avoid race conditions)
