this is a performance optimization. it brings in a "stat generation".
for now it's disabled by default so we retain previous behavior. this
stops eina file from opening and stating a file every time you open
... it only does it if stat generation is off, or, if the generation
changed since the last time it opened that file. this makes cache hits
not have a 3 syscall cost (open+fstat+close). this optimizes that
lower end of things path. but .. it comes at a cost. if the file
changes before generation ticks over (which this forces to tick over
every time the loop exits idle by default).
now here is something to ask.
1. should we have this on by default and accept the "inexactness"
since you can eina_file_statgen_next() before any call that would do
i/o to force it to look at the real file stat info...
2. should we tick over every idle enter OR every N idle enters or
every frame we render instead? ... i want to avoid getting a timestamp
or having a timer interrupt often... so what should we do?
at least this introduces the idea, some api's and an env var to turn
this on. it definitely cuts down syscalls during things like creation
of widdgets or objects in large batches etc.
Summary:
This was causing problems on non-Linux architectures as eina_file_real_close unmapped not mapped data. Added a "copied" flag to Eina_File which is set on eina_file_virtualize (on copied data), and tested for when eina_file_real_close does the unmap. I'm surprised Linux allowed this. Certainly all of the BSDs crashed with the previous behaviour.
@fix T5479
Test Plan: Example inlcude Rage and Enlightenment Thumb on BSD systems which use eina_file_virtualize with emotion to obtain album artwork.

Summary: CreateFileMapping return handle. The handle before use is always closed. This handle can be immediately closed after use.

This caused functions from eina_util to be undefined at compile time.
The compiler would make implicit casts of return values into ints,
which had major side effects (e.g. segfault edje_cc)

Summary:
I've combed through the Eina source files and made enhancements to the
documentation, including:
- Document the undocumented
- Fixed some errors in Doxygen markup
- Moved some function documentation from implementation (.c or .x) to definition
(.h)
- Edited some of the entries to improve clarity

The lock on the main hash was taken to late (after we took the decision
to remove the targeted Eina_File from the cache), this means it was possible
to get an Eina_File from the cache that was going to be removed. This patch
attempt to fix that potential race condition.
Hopefully should fix T461.
