32767 srclocs insufficient

[mafemergency]

the documented srcloc limit[1] of 65534 is insufficient for some programs and i'd like to request bumping it up to 23 bits or more

further, on 0.8.2 - unable to test on a more recent version but it does appear to still be relevant - an assert[2] gets tripped after 32767 srclocs. taking a quick glance and i found uint16_t and int16_t being used interchangeably for srclocs in various structures in TracyView and TracyWorker.

What is the use case for having that many source locations?

[mafemergency]

we have game servers written in an interpreted language where every function is automatically instrumented. some servers have more than 65,535 functions. a typical profiled session might last 3 hours and have 1.4 billion zones (function calls). so i'm sympathetic to the memory bloat this could cause as we have traces that require 40GB+ memory and 20GB+ storage and it's painful.

Ok, having 24 bits for this may be reasonable then.

For performance reasons there are some max-num-of-src-locs sized tables used in the profiler. Going to full 24 bits may be unwanted, as it would make each of these 64 KB tables require 16 MB instead.
