Always support debugging and profiling.
This eliminates the use of the WITH_DEBUGGER and WITH_PROFILER
conditional compilation flags. We've never shipped a device without
these features, and it's unlikely we ever will. They're not worth
the code clutter they cause.
As usual, since I can't test the x86-atom code I left that alone and
added an item to the TODO list.

Fix build breakage caused by the countInstancesOfClass change.
There is an apparent visibility skew between passion-eng and sim-eng
builds. On sim-eng, the contents of Heap.h are globally visible but
on passion-eng this is not the case. To resolve this issue, I have
moved the offending declarations to alloc/Alloc.h which is directly
exported from Dalvik.h.

Add a method for counting the extant instances of a class.
This facility should supersede the use of finalizers in computing
instance counts for the "adb shell dumpsys meminfo" reports.

Allow heap dump requests with a FileDescriptor arg.
Part of a larger change to allow "am" to initiate hprof heap dumps.
The original implementation wrote data to a temp file, because we
compute the second part first while doing GC work. Now all paths
work like DDMS, writing all data to a memstream and then copying it
out to a file at the very end.
Also, fix a potential fd leak on failure in the profiling code.

dvmCreateStringFromCstrAndLength.
The only valid argument would be ALLOC_DEFAULT, so drop the parameter.

Fix misuse of ALLOC_DONT_TRACK.
The internal String creation function doesn't allow ALLOC_DONT_TRACK.
This changes the call to use ALLOC_DEFAULT and then explicitly release
the tracked allocation.

Add class init stats to alloc counters (API change).
Add calls to retrieve class initialization stats via the allocation
count mechanism.
Also: deprecate a method that is never used, and a redundantly declared
default filename that begins with "/sdcard".

Add support for streaming hprof dumps.
This adds the dumpHprofDataDdms method, which generates the hprof dump
in RAM and then spits the whole thing at DDMS. The idea is to avoid
touching /sdcard, since not all apps have permission to do that.
This rearranges hprofShutdown() a fair bit. It used to re-use a context
struct, saving interesting bits to local variables before zapping it;
now we just create a second context struct and free both at the end.
For bug 2092855.

Add streaming method profiling support.
The goal is to allow DDMS to start/stop method profiling in apps that
don't have permission to write to /sdcard. Instead of writing the
profiling data to disk and then pulling it off, we just blast the whole
thing straight from memory.
This includes:
- New method tracing start call (startMethodTracingDdms).
- Rearrangement of existing VMDebug method tracing calls for sanity.
- Addition of "vector" chunk send function, with corresponding
update to the JDWP transport function.
- Reshuffled the method trace start interlock, which seemed racy.
- Post new method-trace-profiling-streaming feature to DDMS.
Also:
- Added an internal exception-throw function that allows a printf
format string, so we can put useful detail into exception messages.
For bug 2160407.

of various reference tables to be dumped. Currently it's the local,
global, and pinned array tables from JNI.

Added VMDebug.crash() (hidden).
This call prints the stack trace for the current thread, and then
crashes the VM so you can see the native stack trace too. Useful for
figuring out "how did I get here?" situations.

Add FileDescriptor variation of startMethodTracing().
This is for bug #1829561 ("am profile" with bad filename kills process), which
will allow the am command to take care of opening the file and handing the
resulting fd over to the process to be profiled.

AI 144931: Added a (hidden) way to "pre-cache" register maps.
The 50 methods that appeared on the GC stacks of the most applications
require 13KB of native heap for their uncompressed register maps, and
the full set took 5ms to uncompress. Pre-computation doesn't represent
a significant improvement in space or time, at the cost of a big pile
of strings in ZygoteInit.
I'm leaving the method in ZygoteInit, but it's not called, and the
static final String[] of method descriptors is empty. We may want to
revisit this later.
