Keir Fraser e157ca3585 Merge per-board msel_pins with user_pins 
This allows users to modify pins that they are not using for MSEL
purposes. Additionally it allows any defined user pin to be used
for MSEL purposes. Specifically, this will allow user pin 6 to be
used as a fourth drive-select line on the Shugart bus.

Keir Fraser 955ccb910d usb: Do not delay 500ms when mode-switching (USB disconnect/reconnect) 
This is not required by the USB spec and in fact seems to make
re-connection *more* unreliable when connected via a USB hub.

Keir Fraser 45821dee07 New intrinsic "unreachable()" to indicate unreachable code points 
This allows better compiler optimisation, while also including an
ASSERT() for debug builds.

Keir Fraser 8b8d4a61cf WRITE_FLUX: Hard-sector index detection 
Expected sector timing is specified to the WRITE_FLUX command. This
allows detection of short sector times, which indicate the true
track start ("track index"). This allows write cueing as for
soft-sectored disks.

Keir Fraser 5b0857791f New delay parameter: index_mask 
Allows configuration of post-trigger INDEX mask time in microseconds
(0-65535). Some drives may need much longer than the default, if
there is sensor-switch bounce on trailing edge of the INDEX pulse.

Keir Fraser 191d68f41b usb: Fix device_qualifier descriptor length 
The descriptor was missing the bReserved field, which must be zero.
This resulted in an out-of-bounds array copy when transmitting the
device_qualifier descriptor, and possible transmission of garbage
for the bReserved field.

This is based on PR #5 created by kimstik@github

Keir Fraser b41091017c Fix GCC 12 infinite loop in strlen 
Strlen was jumping to strlen as part of -ftree-loop-distribute-patterns.
Seems this sort of issue can be common and generally fixed with
-fno-builtin. However, some of those optimizations may be useful and I
don't think our semantics for the functions are wildly different than
the standard, so I'm fixing this surgically with
-ftree-loop-distribute-patterns to just util.c. That may be the wrong
call, so if this bites us again, let's go more aggressive.

FlashFloppy GitHub issue 660.]

It is also equivalent to part of PR #5 created by kimstik@github]

Keir Fraser 0a38ab8846 V4: Further restrict duplication of Act LED to TXO 
Only the original V4 board requires this. The V4.1 board has a pin
header for the original Act signal.

Also make it clear that the duplication happens only on 403(A)
MCUs. It is not possible on 415 as it affects USB operation.
