aced667f48 Undo hacks to meant to get around string formatting limitations
The new vuprintf makes unnecessary workarounds due to formatting
limitations. I checked grep output for whatever appeared to fit
but it's possible I missed some instances because they weren't
so obvious.

Also, this means sound settings can dynamically work with any
number of decimals rather than the current assumption of one or
two. Add an ipow() function to help and take advantage of dynamic
field width and precision. Consolidate string formatting of sound
settings.

b2a373eb64 Replace fp_sqrt function with one that only uses shift, or and sub.
Simply extends the current isqrt() to be able to do fractional bits
and improves the initial estimate using clz(). iqrt() itself is
no more and is equivalent to fp_sqrt(x, 0). The original also had
a small bug where the guess comparision should have been >=, not >.

Uses no large integer math or division and is very accurate
(simply returns a truncated fraction).

d566fd5209 Revert "Don't set CORE_GCSECTIONS in fixedpoint.make."
While it made the mini2g not crash during startup anymore further tests showed
that other mini2g devices still exhibit the crash, or end up with a "No
partition found" error; furthermore  the device tested first still crashes on
USB disconnect. Therefore the change doesn't really help with the problem, and
at the expense of increasing binary size for all other targets there is no
point in keeping it for now.

This reverts commit 850491a043.

850491a043 Don't set CORE_GCSECTIONS in fixedpoint.make.
fixedpoint.make is not a subdir Makefile but a lib Makefile. Setting
CORE_GCSECTIONS in it will affect the final link and make it always use
--gc-sections (for SWCODEC Rockbox), since libfixedpoint is always needed
(bootloader and HWCODEC don't use libfixedpoint).

Fixes FS#12857.
