uml: tidy libc code

Browse Source 
This patch lays some groundwork for the next one, which converts calls to
os_{read,write}_file into {read,write}, by doing some tidying in the affected
areas.

do_not_aio gets restructured to make the final result a bit cleaner.

There are also whitespace and other formatting fixes, fixes in error messages,
and a typo fix.
