We need to check files for magickload with our sniffer as well as the
imagemagick one.

much faster ismagick
...
We used to Ping files to see if IM would load them, but this can be
extremely slow for file formats like ARW.
Instead, use GetImageMagick() ... it just checks the magic number.

fix memleak in magick6load
...
IM ExceptionInfo were not being freed correctly. This patch
adds a small wrapper function and uses it to allocate and free all IM
exception objects.
Tested with im 6.9 and gm 1.3.

fix tga header read
...
When you ping() an image with imagemagick to get the header, some format
loaders (eg. TGA) don't set all the fields. In this case,
image->colormap was not set and that made GetImageChannelDepth() crash.
Work around this, at least in this case, by allocating a colourmap
ourselves if none is set.

move magicksave write struct into class
...
magicksave used to have its own Write struct to track write state.
Instead, keep the write state in the save class.
break the magick6/magick7 compat wrappers out into a separete file so they
can be shared with the loaders.
small style changes.
