Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
EAPI was designed to be able to pass
`__attribute__ ((visibility ("default")))` for symbols with
GCC, which would mean that even if -fvisibility=hidden was used
when compiling the library, the needed symbols would get exported.
MSVC __almost__ works like GCC (or mingw) in which you can
declare everything as export and it will just work (slower, but
it will work). But there's a caveat: global variables will not
work the same way for MSVC, but works for mingw and GCC.
For global variables (as opposed to functions), MSVC requires
correct DSO visibility for MSVC: instead of declaring a symbol as
export for everything, you need to declare it as import when
importing from another DSO and export when defining it locally.
With current EAPI definitions, we get the following example
working in mingw and MSVC (observe it doesn't define any global
variables as exported symbols).
Example 1:
dll1:
```
EAPI void foo(void);
EAPI void bar()
{
foo();
}
```
dll2:
```
EAPI void foo()
{
printf ("foo\n");
}
```
This works fine with API defined as __declspec(dllexport) in both
cases and for gcc defining as
`__atttribute__((visibility("default")))`
However, the following:
Example 2:
dll1:
```
EAPI extern int foo;
EAPI void foobar(void);
EAPI void bar()
{
foo = 5;
foobar();
}
```
dll2:
```
EAPI int foo = 0;
EAPI void foobar()
{
printf ("foo %d\n", foo);
}
```
This will work on mingw but will not work for MSVC. And that's why
EAPI is the only solution that worked for MSVC.

This seems to have been gone a long time ago and only references left
that have not been disturbing the build. Time to clean up!

Summary:
integrate mman.h to make Evil private to the EFL, as mman.h does not exist on Windows. After a discussion with raster, i include sys/mman.h only on non Windows platform.
One issue, though, is that src/modules/emotion/generic/Emotion_Generic_Plugin.h has inlined functions using mmap()
Test Plan: compilation on Windows

we can't sensibly use things like massif to track memory if we bypass
itr with mmaping -1 fd anonymous memory... so if built with valgrind
support and running under valgrind, use malloc/calloc and free so
these tools actually do something useful for these bits of memory.
Eina Debug is a new layer aimed for EFL debugging. It offers scalability
by allowing registration of operations not specific to EFL core.
The protocol is simple and the APIs try to provide as much
functionalities/freedom as possible.
we set stack var to 0 even if evlog was off and thus didn't use it.
this cleans up the evlog func a bit and also moves locking until later
so it's locked for the minimum period to punt something into the log
buffer. it's an improvement, but no bug fix.
If we're not logging events this generates a lot of wasted system
calls. They probably don't amount to much, but it's trivial to
get rid of them, and they make a mess when logging with strace.
this checks for clock_gettime + CLOCK_MONOTONIC or CLOCK_REALTIME at
evlog init to avoid a cmp+brang and l1 instr cache hit every get.
slightly less overhead when this is on.
