fabeb5b9c7f678ab3bc24c1860f8514ac52bb56f fuzz: Disable shuffle when merge=1 (MarcoFalke)
Pull request description:
This should hopefully help make the deletion of fuzz inputs more deterministic.
My tests (N=1) revealed that without this patch 7000 files differ (https://github.com/bitcoin-core/qa-assets/pull/44#issuecomment-768841467). With this patch, "only" 2000 files differ.

fa3fa27c45618bcd8e325b27728b5f6c175d1a03 fuzz: Remove option --export_coverage from test_runner (MarcoFalke)
aaaa055ff72a33241a3fdc2308d77bcbf51c262d fuzz: Add option to merge input dir to test runner (MarcoFalke)
fa4fa88d7648bfeb75fac941cdff79dcc38affbf doc: Remove --disable-ccache from docs (MarcoFalke)
Pull request description:
This is mainly useful for myself to merge pull requests like https://github.com/bitcoin-core/qa-assets/pull/4
I thought it wouldn't hurt to share the code.
Also remove the `--disable-ccache` from the docs to speed up builds when developing fuzzers.
