- implement CertGetCRLFromStore, with tests
- update tests for CRL revocation functions to show name isn't checked

- fixed regression when looking for winebuild's special symbols in ELF symtab
- STT_NOTYPE is still accepted as a valid symbol type (on top of STT_FUNC and STT_OBJECT)

We cannot trust 'mkdir -p' to set the proper permissions on parent
directories. So create them manually.
Fix handling of paths containing spaces.
Properly prefix the path with './' if it starts with a '-'.
Stop trying to create a path after the first error.

Also use the whole device surface if one of the extents is zero or 
negative and the mapping mode is MM_ANISOTROPIC or MM_ISOTROPIC.
New tests.

We are only checking against GL_MAX_TEXTURES when binding samplers,
