Fix ZSTD_f_zstd1_magicless for small data
...
* Fix `ZSTD_FRAMEHEADERSIZE_PREFIX` and `ZSTD_FRAMEHEADERSIZE_MIN` to
take a `format` parameter, so it is impossible to get the wrong size.
* Fix the places that called `ZSTD_FRAMEHEADERSIZE_PREFIX` without
taking the format into account, which is now impossible by design.
* Call `ZSTD_frameHeaderSize_internal()` with `dctx->format`.
* The added tests catch both bugs in `ZSTD_decompressFrame()`.
Fixes #1813 .

[libzstd] Fix decompression dictionary bugs and clean up initialization
...
Bugs:
* `ZSTD_DCtx_refPrefix()` didn't clear the dictionary after the first
use. Fix and add a test case.
* `ZSTD_DCtx_reset()` always cleared the dictionary. Fix and add a test
case.
* After calling `ZSTD_resetDStream()` you could no longer load a
dictionary, since the stage was set to `zdss_loadHeader`. Fix and add
a test case.
Cleanup:
* Make `ZSTD_initDStream*()` and `ZSTD_resetDStream()` wrap the new
advanced API, and add test cases.
* Document the equivalent of these functions in the advanced API and
document the unstable functions as deprecated.

benchfn dependencies reduced to only timefn
...
benchfn used to rely on mem.h, and util,
which in turn relied on platform.h.
Using benchfn outside of zstd required to bring all these dependencies.
Now, dependency is reduced to timefn only.
This required to create a separate timefn from util,
and rewrite benchfn and timefn to no longer need mem.h.
Separating timefn from util has a wide effect accross the code base,
as usage of time functions is widespread.
A lot of build scripts had to be updated to also include timefn.
