Limit server query space to 8K entries.
...
In the default configuration this limit is unlikely to be hit. On Windows the
send buffer is 64 KB, which results in ~5K entries. On Linux the buffer is a
bit higher and the number of entries is lower than 7K.

Fix samples order on save, not load.
...
Sorting samples during load was a major mistake, as three different background
processing threads were concurrently accessing the samples table, and it was
being sorted in one of them!

Detect context switch callstack samples.
...
Context switch callstack samples are not included in the sampling data
statistics (as these don't represent random sampling), but are rather put into
a separate dedicated data structure.
For this to work, a complete context switch data has to be available for the
callstack timestamp. There is no guarantee it will be present at the time it
is needed, so a second structure is added to allow postponing qualification of
callstacks.
