Nick Terrell 27498ff00f Reduce stack usage of ZSTD_buildCTable() 
It is a stack high-point for some compression strategies and has an easy
fix. This moves the normalized count into the entropy workspace.

Nick Terrell 7736549bea [bug-fix] Make simple single-pass functions ignore advanced parameters 
The simple compression functions are intended to ignore the advanced
parameters, but they were accidentally using them. All the
`ZSTD_parameters` were set correctly, but any extra parameters were
used as-is. E.g. `ZSTD_c_format`.

This PR makes all the simple single-pass functions listed below ignore
the advanced parameters, as intended.

* `ZSTD_compressCCtx()`
* `ZSTD_compress_usingDict()`
* `ZSTD_compress_usingCDict()`
* `ZSTD_compress_advanced()`
* `ZSTD_compress_usingCDict_advanced()`

It also adds a test case that ensures that each of these functions
ignore the advanced parameters.

Nick Terrell c62eb05964 [lib] Set appliedParams.compressionLevel correctly 
Forward the correct compressionLevel to the appliedParams in all cases.
It was already correct for the advanced API, so only the old single-pass
functions needed to be fixed.

This compression level is unused by the library, but is set so that the
tracing framework can consume it.

Nick Terrell e59c9459a5 [trace] Keep track of a uint64_t tracing context 
The most common information that you want to track between begin() and
end() is the timestamp of the begin function, so you can measure the
duration of the (de)compression call. Allow the tracing library to put
this information inside the `ZSTD_TraceCtx`, so it doesn't need to keep
a global map in this case. If a single uint64_t is not enough, the
tracing library can return a unique identifier (like the context
pointer) instead, and use it as a key in a map.

This keeps the simple case simple.
