py3: only flush before prompting during interactive patch filtering
Follows up on c9093ae8d6c4. It's enough to flush just before each
prompt.

fuzz: new target to fuzz jsonescapeu8fast
This code just feels complicated enough we should go ahead and give it
a dedicated fuzzer: we've found bugs in similar things before.

fuzz: new fuzzer for fncache-related functions
Not all of these are strictly fncache-related, but they all have th
same signature and similar-enough behavior that we may as well fuzz
them together. No obvious bugs for once, but these felt like they were
just complicated enough to cover.

fuzz: new fuzzer for dirs.c
This found a six-year-old bug immediately, and then I put it through a
few CPU-days of time before sending it.

dirs: fix trivial over-read of input data
This code, introduced in 8c0a7eeda06d, was intentionally over-reading
an input string to avoid getting a shared string object for a one-byte
input. Unfortunately with an empty input (like in the case of a fuzzer
getting started) this was a trivial over-read and triggered an
AddressSanitizer failure.
I went out of my way to make sure the code still does the
copy-avoidance tricks. I don't think this change will cost us much
performance since the one-character strings should be cached
aggressively anyway.

sidedatacopies: deal with upgrading and downgrading to that format
This is quite useful to test this on real life data.

sidedatacopies: move various copies related function to the copies modules
We will need to access these logic form the copies module. So we move them from
their higher level module to the lower level `copies` module. We cannot use them
from their top level module as it would create cycles.

copies information from the changelog sidedata.
