6735283d8f os: Don't require an on-stack buffer
This allows urandom requests of even 100k bytes to succeed on a fresh
VM session on a Metro M4 express.

Compress all translated strings with Huffman coding.
This saves code space in builds which use link-time optimization.
The optimization drops the untranslated strings and replaces them
with a compressed_string_t struct. It can then be decompressed to
a c string.

Builds without LTO work as well but include both untranslated
strings and compressed strings.

This work could be expanded to include QSTRs and loaded strings if
a compress method is added to C. Its tracked in #531.

a0058e6712 Introduce a random module that is a subset of CPython's random. It
also initializes in the same way where it takes from a true random
source when available through os.urandom(). After initializing, it
produces deterministic results until the seed is set.

This replaces urandom!

Fixes #139.

778e975936 Split uos module into os and storage.
os is a subset of CPython's os. storage contains additional
file system mounting functionality based on UNIX's mount
management.
