24c20d188e esp_rom: remove functions which depend on sizeof(struct stat)
...and all their callers.

With the upcoming switch from sizeof(time_t)==4 to sizeof(time_t)==8,
sizeof(struct stat) is also increasing.

A few newlib functions present in ROM allocate 'struct stat' on the
stack and call _fstat_r on this structure. The implementation of
fstat is provided in ESP-IDF. This implementation will often do
memset(st, 0, sizeof(*st)), where st is 'struct stat*', before setting
some fields of this structure. If IDF is built with sizeof(st)
different from sizeof(st) which ROM was built with, this will lead
to an out-of-bounds write and a stack corruption.

This commit removes problematic ROM functions from the linker script.
Here are the functions which allocate 'struct stat':
* _isatty_r (in ROM)
* __swhatbuf_r, called by __smakebuf_r, called by __swsetup_r and
  __srefill_r (in ROM)
* _fseeko_r (not in ROM)
* glob2 (not in ROM)
* _gettemp (not in ROM)

As a result, these functions are used from libc.a, and use correct
size of 'stat' structure.

b7b9ea4361 newlib: add _RETARGETABLE_LOCKING support
This adds support for the retargetable locking implementation in
newlib 3. This feature will be enabled in the future toolchain builds.
With the present version of the toolchain, this code doesn't get used.

When _RETARGETABLE_LOCKING gets enabled, newlib locking implementation
will be modified as follows:

- Legacy ESP-specific _lock_xxx functions are preserved. This is done
  because ROM copies of newlib in ESP32 and ESP32-S2 rely on these
  functions through the function pointer table. Also there is some
  code in IDF which still uses these locking functions.

- New __retarget_lock_xxx functions are introduced. Newlib expects
  these functions to be provided by the system. These functions work
  pretty much the same way as the ESP-specific _lock_xxx functions,
  except one major difference: _lock_acquire receives the lock pointer
  by value, and as such doesn't support lazy initialization.

- Static locks used by newlib are now explicitly initialized at
  startup. Since it is unlikely that these static locks are used at
  the same time, all compatible locks are set to point to the same
  mutex. This saves a bit of RAM. Note that there are still many locks
  not initialized statically, in particular those inside FILE
  structures.

d9a5c8f387 esp32: Use FPU for floating point divide, power, complex multiplications
* Linker was choosing ROM symbols for these, which use integer soft-float
  operations and are much slower.
* _divsf3() moved to IRAM to avoid regressions with any code that does
  integer float division in IRAM interrupt handlers (+88 bytes IRAM)
* Thanks to michal for reporting:

22514c1dd9 cmake: For gcc8 use linker to find paths to libc, libm, libstdc++, etc
Removes the need to know/guess the paths to these libraries. Once we are gcc 8 only, we
can remove -nostdlib and no additional arguments are needed for system libraries.

The catch is: any time IDF overrides a symbol in the toolchain sysroot, we need
an undefined linker marker to make sure this symbol is seen by linker.
