Fix 32-bit BMP loading (RGBA or RGBX)
...
PIL choked on perfectly valid BMP files (32 bits with Alpha). It could not handle valid RGBA masks to determine the raw format.
To clarify things, I:
- Rewrote the `BmpImagePlugin.BmpImageFile` class to be far more readable
- Made error messages more explicit (e.g. say that RLE bitmaps are unsupported)
- Made a readable dict to contain BMP header information
- Kept the existing security checks
- Instead of reading palette info by chunks of 3/4 bytes, read the whole palette info at once and parse the data.
- Now works with BMPv4/5 with Alpha (and can be exported to alpha PNG for example)
- Tested load and save with RGB24, RGB8, RGB8L, RGB32 and RGBA32.
- Tested with one bogus file. File not accepted, as expected.
I wanted to test more BMP formats, but I could not find that many images.
But for all the types I tested, it worked flawlessly.

Special-case opaque pixels in RGBa unpacker
...
Avoid the expensive multiply and divide when the pixel is opaque.
On my system, this change gives a 5.76x speedup loading an opaque image
with this call:
PIL.Image.frombuffer('RGBA', (1000, 1000), buf, 'raw', 'RGBa', 0, 1)
