Kim Woelders 1a6a6b6433 Remove __imlib_AllocateData() w,h args 
im->w and im->h must always be set before __imlib_AllocateData() is
called due to non-immediate loading (__imlib_AllocateData() only
comes in play when the pixel data must be loaded).

Olof-Joachim Frahm (欧雅福) fb0cce4caf tga loader: implement handling of palette 
Summary:
implemented 8 bit color mapped images with 24/32bpp palette.

This is coming from an issue on [[ https://github.com/derf/feh/issues/491 | feh ]] to support indexed TGA images. Written by [[ https://github.com/rofl0r | rofl0r ]], I'm forwarding it because I already have the tools for submission set up.

N.b. I'm not terribly familiar with the particular code style, if there's anything to format differently I'm happy to update.

Test Plan:
- Compared [[ https://0x0.st/zgB4.tga | example file ]] with known good in GIMP, looks okay.
- Tested that said example file doesn't load without this patch (in feh, which uses Imlib2).

Olof-Joachim Frahm (欧雅福) ff3164df37 Check filename before opening archive file. 
Summary:
Decompressing should be the last step, otherwise files that can't even be loaded will take unnecessarily long only to be discarded immediately.

This is in reference to [this issue for feh](https://github.com/derf/feh/issues/477) complaining about long load times in case of accidentally trying to open a big .tar.bz2 archive.

Test Plan: Ran on sample from aforementioned ticket, observed immediate response and no further ill effects.

Alexander Volkov 03665627db Allow to use custom memory management functions for loaded images 
Summary:
... and add imlib_create_image_using_data_and_memory_function().

For example, it allows to load an image in one process and then
pass it through shared memory to another process without extra
memory copy.

Kim Woelders 09d9a95054 Remove pointless im->data checks in loaders 
im->data should always be NULL when entering the load() function.

We can therefore also remove free(im->data) calls before the buffer
is allocated.

Kim Woelders cbc09c0345 XPM loader: Fix potentially uninitialized pixel data 
Pixels with color "none" were composed using uninitialised GB values.

Although the pixels were "correct", as RGB are don't-care when A is 0,
let's not put random data in images and avoid valgrind complaints.

Thanks to Sebastien Ballet for test case.
