The files are only ever generated to .OBJDIR, not to WORLDTMP (as a

Only filter out the PF ioctls if we're building without pf support.
Until now those were always filtered out, so truss did not show symbolic

Our man pages have always indicated that this was supported, but in fact the

This was originally added so that only one of diskmbr.h or diskpc98.h
was chosen and is no longer needed after PC98's removal. However, the
special handling was also broken as it effectively prevented the decoding
of ioctls declared in other headers such as <sys/disk.h> or
<sys/disklabel.h>.
Following up on r320900, where the check for negative count values was
removed, add a check to prevent integer overflow. This is to account that
b_count, b_waiters but most importantly the total number of threads in
the system are signed values.

Create libdl.so.1 as a filter for libc.so.7 which exports public dl*
functions. The functions are resolved from the rtld instead, the goal
of creating library is to avoid errors from the static linker due to
missed libdl. For static binaries, an empty .o is compiled into
libdl.a so that static binaries still get dl stubs from libc.a.
Right now lld cannot create filter objects, disable libdl on arm64
when binutils are not used.

Implement the MMC/SD/SDIO protocol within a CAM framework. CAM's
flexible queueing will make it easier to write non-storage drivers
than the legacy stack. SDIO drivers from both the kernel and as
userland daemons are possible, though much of that functionality will
come later.
Some of the CAM integration isn't complete (there are sleeps in the
device probe state machine, for example), but those minor issues can
be improved in-tree more easily than out of tree and shouldn't gate
progress on other fronts. Appologies to reviews if specific items
have been overlooked.

merge with first commit, various compile hacks.
An oversight in r320742 caused BREs to become sensitive to the branching operator prematurely, which caused
breakage in some limited situations -- namely, those that tried to use branching in a BRE. Most of these scenarios
had already been corrected beforehand to properly use gsed or grep for GNU extensions, so the damage is
slightly mitigated.

EREs closer together. Prepare for this and reduce the diff of libregex changes by
refactoring and combining the top-level parsers for EREs/BREs ahead of time.
Branching functionality has been split out to make it easier to follow the combined
version of the top-level parser. It may also be enabled in the parsing context to make
it easier when libregex enables branching for BREs.
A branching context was also added for the various branching functions and so that
BREs, for instance, can determine if they're the first expression in a chain of expressions
within the current branch and treat '*' as ordinary if so.
This should have no functional impact and negligible performance impact.
