0c13fb818b Initialize rpmalloc in Mem{Alloc,Free}Callstack().
rpmalloc may still be uninitialized here (i.e. if memory allocation/free
is performed before any other tracy operation that would initialize
thread_local data). Since memory allocations are using serialized queue
(which is not held in thread_local section) and obtaining callstack
involves memory allocation, we need to initialize rpmalloc manually.

This won't be a problem when support for zone callbacks becomes online,
because zones are stored in per-thread queues, which initialize
thread_local data before rpmalloc is needed in the Callstack() call.

3b03e849f0 Harden client code against unaligned memory access.
There shouldn't be any changes in generated code on modern
architectures, as the memcpy will be reduced to a store/load operation
identical to the one generated with plain struct member access.

GetTime( cpu ) needs special handling, as the MSVC intrinsic for rdtscp
can't store cpu identifier in a register. Using intermediate variable
would cause store to stack, read from stack, store to the destination
address. Since rdtscp is only available on x86, which handles unaligned
stores without any problems, we can have one place with direct struct
member access.

7424077d70 Store source location in a single object.
Source file, function name and line number are now stored in a const
static container object. This has the following benefits:
- Slightly lighter profiling workload (3 instructions less).
- Profiling queue event size is significantly reduced, by 12 bytes. This
  has an effect on all queue event types.
- Source location grouping has now no cost, as it's performed at the
  compilation stage. This allows simplification of server code.
The downside is that the full source location resolution is now
performed in two steps, as the server has to query both source location
container and strings contained within. This has almost no real impact
on profiler operation.
