f953b98285 Try to fix tests
Choked on roundtrip, where a P;1 image was returned instead of a 1 image.

7b657f6887 Fix for all good_tests
Fixed loading of all types of provided images (+rgba). Added edge case where the header is reported as 40 bytes long with BITFIELDS (they start past the 40 bytes of the header). Loading fails for RLE, but IIRC, they're unsupported so it's normal.

877c138e21 1bpp BMP fix
It appears that
{{{
  The handling of 1bpp bitmaps is a little complicated.
  When reading 1bpp bitmaps, the palette is ignored.
  1's are considered foreground, and they are considered black.
  0's are considered background, and they are considered white.
}}}
so the raw mode has to be `1;I`

456bd96565 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.

77b020b374 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)
