with more JS code that is loaded into the VM before writing the snapshot. Get
rid of the hard coded limit on the partial snapshot cache size. This change
disables most of the serializer tests for the snapshot build of the VM: It's
getting too complicated to support both booting from a snapshot and then
creating a new snapshot from the same VM or loading more code with another
snapshot in the same VM.

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.

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.

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.

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.

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.
