Now that we have proper 32-bit compat support, remove COMPAT_32BIT
ifdefs to allow 32-bit code to use the 64-bit layout of USB ioctl
structs and struct usb_fs_endpoint.
This includes the removal of redundant alignment directives that had
no effect in practice.

This codepath used uint64_t's in place of pointers in structs and
arrays to allow 32-bit code to use 64-bit version of ioctls. Now
that we support 32-bit compat natively this is no longer needed.

Unlike most 32-bit compatability code, this isn't just a simple thunk
in the ioctl code. An ioctl (USB_FS_INIT) is used to install a
pointer to an array of usb_fs_endpoint structs which are then used
by the ugen fifo code. These struct contains an array of pointers
which requires translation. We change the interfaces around
struct usb_fs_endpoint as follows:
- We store the size of struct usb_fs_endpoint in struct usb_fifo
in the USB_FS_INIT handler so we know the ABI of the userspace
array.
- APIs to manipulate userspace struct usb_fs_endpoint objects now
take a struct usb_fifo and an index rather than a pointer to
the object. This allows most code to remain oblivious to the
different struct usb_fs_endpoint sizes.
- Add ugen_fs_copyin() which copies the struct usb_fs_endpoint
from userspace, thunking it to the native size if required.
- Uses of struct usb_fs_endpoint's ppBuffer member are now
via ugen_fs_getbuffer() which produces a native pointer.
- Updates to userspace are now handled by ugen_fs_update().
For clarity, single, fixed-sized members now are accessed with
fueword/suword rather than copyin/copyout.

Use thunks or alternative access methods to support ioctls without
the COMPAT_32BIT hacks that store pointers in uint64_t's on 32-bit
platforms. This should allow a normal i386 libusb to work.
On CheriBSD, the sizes of the structs will differ between CheriABI
(the default) and freebsd64 no matter what so we need proper compat
support there. This change paves the way.

In particular, we need to initialize efbuf->flags, since
export_vnode_to_sb() loads that field. This was mostly harmless since
the flag only determines whether the output kinfo_file is packed, and
KERN_PROC_CWD only ever emits a single kinfo_file anyway.

getf() on FreeBSD calls _sx_slock(), _sx_sunlock() and fget_locked().
Furthermore, it does not set the per-core fault flag, meaning it
usually ends up in a double fault panic once getf() does get called,
especially from fbt.
Reviewing the DTrace Toolkit + a number of other scripts scattered
around FreeBSD, I have not been able to find one use of getf(). Given
how broken the implementation currently is, we disable it until it
can be implemented properly.
Also comment out a test in aggs/tst.subr.d for getf().

syslog(3) was recently change to support larger messages, up to 8KB.
Our syslogd handles this fine, as it adjusts /dev/log's recv buffer to a
large size. rsyslog, however, uses the system default of 4KB. This
leads to problems since our syslog(3) retries indefinitely when a send()
returns ENOBUFS, but if the message is large enough this will never
succeed.
Increase the default recv buffer size for datagram sockets to support
8KB syslog messages without requiring the logging daemon to adjust its
buffers.

This forces everything to be regenerated by marking makesyscalls.lua
as .PHONY, which may be helpful in, e.g., rebase scenarios, which may
have unexpected effects on mtimes but still really need a regen.
For now we apply this to the default sysent target, which is ran
manually and not as a part of buildkernel. We can reconsider this if
someone manually running it has issues with the runtime, but the top
level sysent target can run each in parallel; I recommend -j4 or so.
