The partition_name field is an array, so can never be NULL itself. Check only
the first byte instead.
This was found when test building with clang, but I'm not sure how it passes
gcc's warnings either.
The blacklist library can accept a function to use for logging,
defaulting to vsyslog(), if no function is specified. Make the
blacklist library use strerror(errno) explicitly, instead of %m,
so that the passed in function does not need to support the
syslog specific placeholder.
This matches a change already submitted and accepted upstream.

The addition of the referenceCount to __cxa_allocate_exception put the
unwindHeader at offset 0x58 in __cxa_exception, but it requires 16-byte
alignment. In order to avoid changing the current __cxa_exception ABI
(and thus breaking its consumers), add explicit padding in the
allocation routines (and account for it when freeing).
This is intended as a lower-risk change for FreeBSD 11. A "more correct"
fix should be prepared for upstream and -CURRENT.

_Unwind_Exception is required to be double word aligned. GCC has
interpreted this to mean "use the maximum useful alignment for the
target" so follow that lead.

FreeBSD uses LLVM's libunwind on FreeBSD/arm64 today (and we expect to
use it more widely in the future) and it requires the EH frame segment

For historical reasons Darwin/i386 has ebp and esp swapped in the
eh_frame register numbering. That is:
Darwin Other
Reg # eh_frame eh_frame DWARF
===== ======== ======== =====
4 ebp esp esp
5 esp ebp ebp
Although the UNW_X86_* constants are not supposed to be coupled to
DWARF / eh_frame numbering they are currently conflated in LLVM
libunwind, and thus we require the non-Darwin numbering.

Instead of changing the whole course to another POSIX-permitted way
for consistency and uniformity I decide to completely ignore missing
regex fucntionality and focus on fixing bugs in what we have now,
too many small obstacles we have choicing other way, counting ports.
Corresponding libc changes are backed out in r302824.

Instead of trying to expand whole range at regcomp() stage as we do,
GNU regex allocates separate ranges [start,end] set each character
is checked against, so collation is possible and turned on for ranges here.
When something like that will be implemented or our obsoleted regex code
will be replaced to something like TRE, and in case we decide to use
collation in [a-z] ranges, all changes related to r302512 can be backed out,
but now we need consistency.

I try to keep the change minimal to not touch contribed code much.
