The cd handles should be collected as list of partitions. Some systems also
provide base name for block device (like PciRoot(0x0)/Pci(0x5,0x0)), we need
to be careful about those.
To make out life a bit easier, we prepare not just an array of handles, but we
allocate pdinfo struct for each handle and devicepath, then we can simplify
our work to sort the devices.

Add FAT support to makefs by copying some files from sys/fs/msdosfs/ and
updating others with changes from NetBSD.
The six files copied from sys/fs/msdosfs at r348251 and modified are:
denode.h direntry.h fat.h msdosfs_fat.c msdosfs_lookup.c msdosfsmount.h
I would prefer to avoid the duplication, but reluctance to doing so was
expressed in a previous review (D11197); for now copy the files and
revisit in the future.

Otherwise the mutex needs to be dropped when copying out the midistat
sbuf, leading to a race which allows one to read kernel memory beyond
the end of the sbuf buffer.

Rework recursive_timed_mutex so that it uses __thread_id instead of
using the lower-level __libcpp_thread_id. This is prep for fixing
PR42918. Reviewed as https://reviews.llvm.org/D65895
Pull in r368916 from upstream libc++ trunk (by Marshall Clow):
Fix thread comparison by making sure we never pass our special 'not a
thread' value to the underlying implementation. Fixes PR#42918.
This should fix std:🧵🆔:operator==() attempting to call
pthread_equal(3) with zero values.

In Seventh Edition UNIX, the last pointer passed to free() was
guaranteed to not actually have been freed allowing memory to be
"compacted" via the following pattern:
free(foo);
foo = realloc(foo, newsize);
Further, Andrew Koenig reports in "C Traps and Pitfalls" that the
original realloc() implementation required this pattern.
The C standard is clear that this is Undefined Behavior. Modern
allocators don't support it and no portable code could rely on it so
remove this support.
Note: the removed implementation contains an off-by-one error and if
an item isn't found on the freelist, then twice as much memory as the
largest possible allocation will be copied.

order to have struct mii_data available. However, it only really needs
a forward declaration of struct mii_data for use in pointer form for
the return type of a function prototype.
Custom kernel configuration that have usb and fdt enabled, but no miibus,
end up with compilation failures because miibus_if.h will not get
generated.
Due to the above, the following changes have been made to usb_ethernet.h:
* remove the inclusion of mii headers
* forward-declare struct mii_data
* include net/ifq.h to satify the need for complete struct ifqueue

We suffer at least one round trip ACK latency every command / packet that
GDB has to send and receive, and the response format for 'info threads'
supports packing many threads IDs into a single packet, so do so.
Adds and uses a new API, gdb_txbuf_has_capacity(), which checks for a
certain number of bytes available in the outgoing txbuf.
On an example amd64 VM, the number of RTTs to transmit this list is reduced
by a factor of 110x. This is especially beneficial with recent GDB, which
seems to request the list at least twice during attach.
