Fold expressions are more expressive and probably produce better code than the
older template-recursion and initializer_list patterns.

When we are running from a network drive the new feature in part 1 doesn't work.
So this uses DuplicateHandle instead of OpenThread to get the thread handle used
by the profiler.
It also removes a DuplicateHandle THREAD_ALL_ACCESS call that also fails and a
DuplicateHandle to get a real process handle, which only seems to have been to
fix something on Windows XP.
The handle passed in is always the profiler one, so already has the necessary
permissions. If no thread handle is passed then the pseudo handle is used.

Actual implementation of the entry reader and writer.
They expose a very similar API as the original BlocksRingBuffer entry reader&
writer.
(No tests here; In the next patch they will get used instead of the old reader&
writer, and will hence inherit all relevant tests.)

ProfileBufferEntrySerialization.h will contain the entry reader and writer.
This patch creates the file with renamed copies of the (de)serializers from
BlocksRingBuffer; there shouldn't be significant code changes, this `hg cp` will
help keep their history. See next patch for how they will actually be used.

The blocklist variable `BROWSER_PROCESS` did not work as expected. Entries
defined there were blocked not only in the browser process but also in the
child process.
This patch makes sure entries in `BROWSER_PROCESS` are blocked only in the
browser process.

Apps targeting SDK 29 are not allowed to open /dev/ashmem directly, and
instead must use NDK functions. Those functions are only available in
SDK 26 and higher, so we need this shim to use the functions if they
are available, else fallback to opening /dev/ashmem directly.

In the current Win 8.0, these functions both start with a RIP-relative JMP (6 bytes) followed by 6 nops (6-bytes), which does not give us the 13-bytes we need for a trampoline so we require the trampoline to fit into 10 bytes.

We copy IAT for ntdll.dll into a new process so that our hook code can use
ntdll's functions even in the early stage. However, IAT can be modified and
some entries may point to an address which is not valid in the child process.
In such a case, we should not copy IAT. One example is Windows compat mode
which redirects some ntdll functions into AcLayers.dll via IAT.
With this patch, we verify each IAT entry and if any of them is outside ntdll,
we give up using the launcher process and start the browser process.

To facilitate the upcoming transition to a new Fission-friendly storage, all
uses of `BlocksRingBuffer::{,Block}Index` are replaced with
`ProfileBuffer{,Block}Index`.

ProfileBufferIndex.h contains:
- `ProfileBufferIndex`, a generic index into a Profiler buffer.
- `ProfileBufferBlockIndex`, an almost-opaque index that should only point at
valid (or expired) blocks.
These will soon be used instead of `BlocksRingBuffer::{,Block}Index`, to make
the transition away from `BlocksRingBuffer` easier.

In x86, our detour handles opcode 83 only when the Mod bits is 3.
When working on another project, I hit the instruction `cmp [ebp+0Ch],1`
where the Mod bits is 1, and it can be easily handled by a small fix.
It turned out my project does not need it, but it'd be good to have this.

GENERATED_FILES now defaults to python3 unless py2=True is specified as
an argument. All existing GENERATED_FILES scripts and GeneratedFile
templates have the py2=True attribute added, so this patch should
effectively be a no-op.
Going forward, individual scripts can be converted to python3 and their
corresponding py2=True attribute can be deleted. In effect, this patch
will be backed out in pieces until all scripts run in python3, at which
point the py2 attribute itself can be removed.
