3c0ce01954 Simplify access to queue producer token. 
Note that calibration loop needs separate token, as the thread_local
instance is created after the profiler (and its calibration loop).

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.

e5ad7d9ac4 GetTime() call can be now inlined. 
No dependencies on either windows.h, or static instance of Profiler.

e1a63dbb53 Drop constant merging check. 
While without constant merging the profiler operates sub-optimally, it's
not that essential to be enabled. And there are problems with it on some
platforms, for example cygwin.

d7914439e9 Use stream compression. 
Previously each data packet was compressed independently. After this
change all new packets reference the previously sent data, which
achieves better compression.

1ea61c2f2c Use LZ4 to compress network data. 
This greatly reduces required network bandwidth, which in effect speeds
up queue processing.

Time to process a single event queue item:

      | Raw data | With LZ4 |
------+----------+----------+
Deque |  6.86 ns |   6.7 ns |
Pack  |  4.03 ns |   4.0 ns |
LZ4   |  ---     |  21.6 ns |
Send  | 214.5 ns |   5.2 ns |
------+----------+----------+
Total | 225.4 ns | 37.58 ns |
