ec58c05f4e Add support for startup data (snapshot) compression.
This is for mobile platforms where application footprint size is
important. To avoid including compression libraries into V8, we assume
that the host machine have them (true for Linux), and rely on embedder
to provide decompressed data.

Currently, only snapshot data can be comressed. It is also possible to
compress libraries sources, but it is more involved and will be
addressed in another CL.

now, the custom call generator stuff is disabled.

90045ddd5e Another step on the way to context snapshots. We can now refer to
objects in the startup heap from a partial snapshot.  This happens
through the partial snapshot cache.  A startup snapshot and a
partial snapshot are created together so that the startup snapshot
contains the partial snapshot cache entries needed.

37d3972429 Fix issue 571: display descriptive names for code objects from snapshot.
As this is only needed for internal profiling (not for DevTools),
the following approach had been chosen:

 - during snapshot creation, positions of serialized objects inside
   a snapshot are logged;

 - then during V8 initialization, positions of deserealized objects
   are logged;

 - those positions are used for retrieving code objects names from
   snapshot creation log, which needs to be supplied to tick processor
   script.

Positions logging is controlled with the new flag: --log_snapshot_positions.
This flag is turned off by default, and this adds no startup penalty.

To plug this fix to Golem, the following actions are needed:

 - logs created using 'mksnapshot' need to be stored along with VM images;

 - tick processor script needs to be run with '--snapshot-log=...' cmdline
   argument.

BUG=571

fb2317b63b New snapshot framework. Doesn't work on ARM yet (code targets
are different).  Is able to deserialize the whole heap and run
some stuff.  Not available as the primary snapshot system yet.

30a0a7de43 Split nested namespaces declaration in two lines in accordance with C++ Style Guide.
This issue was raised by Brett Wilson while reviewing my changelist for readability. Craig Silverstein (one of C++ SG maintainers) confirmed that we should declare one namespace per line. Our way of namespaces closing seems not violating style guides (there is no clear agreement on it), so I left it intact.

44510671e9 Fixed bug in JSObject::GetPropertyAttributePostInterceptor where map transitions would count as properties.
Allowed aliased eval invocations by treating them as evals in the global context. This may change in the future.

Added support for accessing the last entered context through the API and renamed Context::Current to Context::GetCurrent and Context::GetSecurityContext to Context::GetCurrentSecurityContext.

Fixed bug in the debugger that would cause the debugger scripts to be recursively loaded and changed all disabling of interrupts to be block-structured.

Made snapshot data read-only to allow it to be more easily shared across multiple users of V8 when linked as a shared library.
