Felipe Magno de Almeida ccc1849263 eina: Rename EAPI macro to EINA_API in Eina library
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.

Amitesh Singh 2cf24eb304 eina: strbuf - Add strftime related functions
eina_strbuf_append_strftime()
eina_strbuf_insert_strftime()
eina_strbuf_prepend_strftime() - macro

We need these functions for implementing generic format function
interface especially for calander.

Marcel Hollerbach 4d6d177ff7 eina_buf: replace eina_strbuf_free_return with eina_xXxbuf_release
The api name free_return wasnt a good choice so it is changed to
release. This also moves the implementation to binbuf template so it is
available in all buf types.

Marcel Hollerbach 2f1d0fb189 eina_strbuf: add eina_strbuf_free_return
Summary:
For a function which just composes a string with strbuf its quite
usefull to return the string while its freed.

This makes a function like:

{
   Eina_Strbuf *buf;
   char *path;

   buf = eina_strbuf_new();
   eina_strbuf_append(buf, "test");
   eina_strbuf_append_printf(buf, "%s-%d.edj", "test", 0);
   path = eina_strbuf_string_steal(buf);
   eina_strbuf_free(buf);
   return path;
}

To:

{
   Eina_Strbuf *buf;

   buf = eina_strbuf_new();
   eina_strbuf_append(buf, "test");
   eina_strbuf_append_printf(buf, "%s-%d.edj", "test", 0);
   return eina_strbuf_free_return(buf);
}

Which is a bit more handy.

Test Plan: just run make check

Srivardhan Hebbar 95117bc515 eina: Added API to get substring from Eina_Strbuf.
Summary:
This API is analogous to c++ substr. It returns a Eina_Strbuf with
substring of passed buf.
