mkerr: remove legacy guards from generated error headers
In pull request #9333, legacy guards were added to the generated
error headers, but the mkerr.pl script was not adjusted accordingly.
So the legacy guards were removed by subsequent `make update` calls.
Fixing the mkerr.pl script properly was disproportionately complicated
by the fact that adding legacy guards only made sense for files which
already existed in version 1.1.1. To keep things simple, it was decided
to drop the legacy guards from the generated headers entirely.

Allow certificates with Basic Constraints CA:false, pathlen:0
Do not mark such certificates with EXFLAG_INVALID although they
violate the RFC 5280, they are syntactically correct and
openssl itself can produce such certificates without any errors
with command such as:
openssl x509 -req -signkey private.pem -in csr.pem -out cert.pem \
-extfile <(echo "basicConstraints=CA:FALSE,pathlen:0")

Fix off-by-1 bug on provider_activate with custom error strings
Starting `cnt` from 1 would work if we weren't using cnt itself to
access elements of the array returned calling the provider callback.
As it is before this commit, we have 2 problems:
- first, in the unlikely case that the incoming array was "empty" (only
contains the terminator item) we would skip past it and potentially
end up with oob reads;
- otherwise, at the end of the while loop, `cnt` will be equal to the
number of items in the input array, not 1 more. We then add 1 more to
the zalloc call to account for the library name item, and we fill all
of it (relying on zalloc to have zeroed the terminator item).
The first read access that will read the list up to the terminator
will result in a OOB read as we did not allocate enough space to also
contain the terminator.
