Summary:
Patch from a series of patches to rename EAPI symbols to specific
library DSOs.
= The Rationale =
This patch is 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
LIBAPI is the only solution that works for MSVC.

Summary: EAPI must be defined to dllexport when building DLL, and to dllimport when using these DLL. To achieve this, define EFL_BUILD for each library and module, and set DLL_EXPORT unconditionally. Static library are and will be not supported

this is done because .eo files are not stable, and in order to stop
people depending on it, its better for now to disable the installation
of them for now.

This uses the meson/ninja depfile functionality + eolian to make
sure proper dependencies between generated files and .eo files
are managed, to ensure consistent re-generation of all generated
files that are affected upon .eo file modification.
For custom rules with multiple outputs, Ninja currently does not
support depfiles. Therefore, split those into two custom rules
so that the depfiles functionality can be enabled. While this
is ugly and slows down the process a little by having to invoke
Eolian twice instead of once, it has to be done and it's still
better than what we had in Autotools anyway.
