Rename hwlock_acquire() to hwlock_acquire_timeout() in preparation for
future changes to the hw-lock API.  Change all uses of the hw-lock API
to reflect this change.

This commit does not introduce any functional changes, except getting
rid of the timeout usage warnings.  This change is no-op, because the
hwlock_acquire() implementation already replaces any non-zero timeout
value with portMAX_DELAY.

With the switch to the new mutex API, hwlock_release() cannot fail under
any circumstances.  To emphasize this, make it return void instead of
int (Previously it just always returned 0).

Reimplement the hw-lock module to use the new mutex API.  This slightly
changes the semantics of locking a hw-lock as the new mutex API does not
allow timeouts.  When a hwlock_acquire() with a (non-infinite) timeout
is attempted, a warning is printed to the serial console.

Additionally, instead of returning -EINVAL on use of a non-existent
hardware lock, the new implementation triggers a firmware panic.

With the increased warning-level, GCC warns about three unused fields in
`bleSmpCfg`:

    - maxAttemptTimeout: Maximum 'Repeated attempts' timeout in msec
    - attemptDecTimeout: Time msec before attemptExp decreases
    - attemptExp: Exponent to raise attemptTimeout on maxAttempts

These should probably be set to sensible values but to make !360
mergeable, explicitly set them to zero for now.

By passing `&resched` instead of just `resched`, the internal comparison

It does not make sense for the filesize to be given as `int`; it cannot

Make the length parameter a `size_t` instead of a `intptr_t`.  A signed
value does not make any sense here and just leads to weird behavior if a
negative value is given nonetheless.

As discussed in card10/firmware!357, we should increase the number of
enabled compiler warnings to catch a lot more silent bugs.  Increase the
meson-global warning level to 2, but excluding the `unused-parameter`
and `old-style-declaration` warnings.  Additionally, disable warnings
for libraries as we cannot fix that code anyway.
