As the pl061 driver can be an interrupt controller attach it earlier in the

Use a new GPIO xref to not conflict with the existing root interrupt

This has three advantages over write(2)/read(2):
* Fewer context switches and data copies
* Mostly preserves a file's sparseness
* On some file systems (currently NFS 4.2) the file system will perform the
copy in an especially efficient way.

getlogin_r is specified by POSIX to to take a size_t len, not int. Fix our
version to do the same, bump the symbol version due to ABI change and
provide compat.
This was reported to break compilation of Ruby 2.8.
Some discussion about the necessity of the ABI compat did take place in the
review. While many 64-bit platforms would likely be passing it in a 64-bit
register and zero-extended and thus, not notice ABI breakage, some do
sign-extend (e.g. mips).

Currently, certctl rehash will just keep clobbering .0 rather than
incrementing the suffix upon encountering a duplicate. Do this, and do it
for blacklisted certs as well.
This also improves the situation with the blacklist to be a little less
flakey, comparing cert fingerprints for all certs with a matching subject
hash in the blacklist to determine if the cert we're looking at can be
installed.
Future work needs to completely revamp the blacklist to align more with how
it's described in PR 246614. In particular, /etc/ssl/blacklisted should go
away to avoid potential confusion -- OpenSSL will not read it, it's
basically certctl internal.

In a side-change that I'm working on to start defaulting src builds to
WARNS=6 where WARNS isn't otherwise specified, GCC6 (and clang, to a lesser
extent) pointed out a number of issues with the resolv tests:
- Global method variable that gets shadowed in run_tests()
- Signed/unsigned comparison between i in run_tests() and hosts->sl_cur
The shadowed variable looks like it might actually be bogus as written, as
we pass it to RUN_TESTS -> run_tests, but other parts use the global method
instead. This change is mainly geared towards correcting that by removing
the global and plumbing the method through from run_tests -> run into the
new thread.
For the signed/unsigned comparison, there's no compelling reason to not just
switch i/nthreads/nhosts to size_t.
The review also included a change to the load() function that was better
addressed by jhb in r365302.
