86ce442607 ports: Add '.frozen' as the first entry in sys.path.
Frozen modules will be searched preferentially, but gives the user the
ability to override this behavior.

This matches the previous behavior where "" was implicitly the frozen
search path, but the frozen list was checked before the filesystem.

e0bf4611c3 py: Only search frozen modules when '.frozen' is found in sys.path.
This changes makemanifest.py & mpy-tool.py to merge string and mpy names
into the same list (now mp_frozen_names).

The various paths for loading a frozen module (mp_find_frozen_module) and
checking existence of a frozen module (mp_frozen_stat) use a common
function that searches this list.

In addition, the frozen lookup will now only take place if the path starts
with ".frozen", which needs to be added to sys.path.

This fixes issues #1804, #2322, #3509, #6419.

5cf71b5596 shared/libc/string0: Don't include string.h, and provide __memcpy_chk.
Some toolchains will have string.h defining various macros which can lead
to compile errors for string function implementations.  Not including
string.h fixes this.

An implementation of __memcpy_chk is provided for toolchains that enable
_FORTIFY_SOURCE.

Fixes issue #6046.

4d546713ec shared: Introduce new top-level dir and move 1st party lib code there.
This commit moves all first-party code developed for this project from lib/
to shared/, so that lib/ now only contains third-party code.

The following directories are moved as-is from lib to shared:

    lib/libc            -> shared/libc
    lib/memzip          -> shared/memzip
    lib/netutils        -> shared/netutils
    lib/timeutils       -> shared/timeutils
    lib/upytesthelper   -> shared/upytesthelper

All files in lib/embed/ have been moved to shared/libc/.

lib/mp-readline has been moved to shared/readline.

lib/utils has been moved to shared/runtime, with the exception of
lib/utils/printf.c which has been moved to shared/libc/printf.c.
