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.

This makes sure that the call to madvise is safe. On Linux it's not too
much of an issue as checks are made inside madvise, and the worst that
can happen is an error is returned (EINVAL). Not great.
But if MAP_POPULATE is not present, as is the case on *BSD, then the
internal function _eina_file_map_populate() is used for the populate
rule. In that case actual data is read and we should make sure not to
trigger a segfault or bus error.
Also, this makes sure that in case of HugeTLB we actually populate all
pages, rather than one page out of 8 (we were jumping by 16Mb instead of
2Mb).
Note: Can we get the size of a HugeTLB at runtime? We're assuming 2Mb
which might very well not be the case!
See: https://wiki.debian.org/Hugepages
Tested by disabling MAP_POPULATE and observing crashes :)

Summary:
Escaping is not happening whenever any escapable characters is coming after
'\t' or '\n'. It will also fix invalid read of 1 byte which happens for string where
last charachter is '\t' or '\n' like "eina\t".
Test Plan:
Take a string like "eina\t ". Observe space which is followed by tab is not getting
escaped.

I believe that all the threads created in our test suite should
be spawned without any special CPU affinity. The default parameter
is not 0 (corresponds to the first CPU, known as CPU 0) but -1.
Similarily the default priority is NORMAL (1), not 0 (URGENT).
This also affects two unused code paths: evas render2 and gl preload.
@fix
The return value from create_file_not_empty was saved but never checked if it
really is 0. Whcih should be the case if we call the function with file_close
true.
Stick to one target per directory and remove prefix from variables,
makes it cleaner and easier to use.
Document variables used and use a more consistent name that matches
CMake properties.
I believe this function is not required and should not be
used by applications. If there is a very good use case to
use your own main freeq, then the API could be added again.
For now, removing the set() is probably the safer option.
Note: the API was introduced in the upcoming 1.19
Built on top of the new 'postponed' free queue, the short-lived
strings API allows users to return new strings without caring
about freeing them. EFL main loop will do this automatically for
them you at a later point in time (at the end of an iteration).
The APIs provided will either duplicate (copy) or more generally
steal an existing string (char *, stringshare, tmpstr, strbuf),
taking ownership of it and controling its lifetime. Those strings
can then be safely returned by an API. From a user point of view,
those strings must be considered like simple const char *, ie.
no need to free() them and their validity is limited to the
local scope.
There is no function to remove such a string from the freeq.
The short lived strings API is not thread-safe: do not send a
short-lived object from one thread to another.
@feature
While this reuses the existing (but new) infrastructure of
eina_freeq, the mode of operation and objective is very different
from the default freeq.
By default, any object added to the freeq is basically already
freed from the user point of view, and the freeq itself only adds
a tiny layer of memory safety by deferring the actual call to free
and optionally filling the memory blob with a pattern ('wwwww...').
This is mostly thread-safe (requires thread-safe free functions).
This new type I called postponed is intended to store objects that
will be short lived. This is not thread safe as the life of the
objects added to this queue depends on the thread that adds to
the queue. The main intent is to introduce a new API for short-lived
strings.
@feature
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.
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.

Summary:
the api returns if a rectangle is positioned above/below/right or left
of a other rectangle.
Code which does simular things are part of verne and e, i think its a good idea to provide api for that.

Some code needs to read directly into eina_binbuf to avoid an extra
copy from eina_binbuf_append* variants.
This can be achieved by using eina_binbuf_expand(), which returns a
write-able slice of the spare bytes. Once they are used,
eina_binbuf_use() should be called to increment "buf->len", which is
used by all other binbuf functions such as eina_binbuf_length_get() or
eina_binbuf_append_slice().
Summary:
Since eina_model was dropped some years ago.
Also a few other points where related stuff is just commented out.

Summary:
the new iterator represents the order from the elements of the original
iterator, elements where the filter callback return false will be
skipped.
The container of this iterator is the original iterator.

this adds eina_freeq api's for c land for deferring freeing of
pointers and can be used a s a simple copy & paste drop-in for free()
just to "do this later". the pointer will eveentually be freed as
eina_shutdown will free the main free queue and this will in turn free
everything in it. as long as the main lo0op keeps pumping things will
og on the queue and then be freed from it. free queues have limits so
if they get full they will clear out old pointers and free them so it
won't grow without bound. the default max is 1mb of data or 16384
items whichever limit is hit first and at that point the oldest item
will be freed to make room for the newest. the mainloop whenever it
finishes idle enterers will add an idler to spin and free while idle.
the sizes can be tuned and aruged about as to what defaults should be.
this also allows for better memory debugging too by being able to fill
freed memory with patterns if its small enough etc. etc.

macOS Sierra provides clock_gettime().
Instead of testing for the Mach kernel to re-implement clock_gettime(),
let first check that clock_gettime() is not already declared. Older OSX
versions will have the Mach-only fallback.
