As we define the ABI, we can just replace BOOL with bool everywhere,
including in ObjFW itself. For the Apple platforms where BOOL and bool
are different, this is not a problem as BOOL and bool are passed and
returned the same way in the ABI.

This still defines BOOL to bool for compatibility, except on AmigaOS and
Wii, which both have its own BOOL type. file: [6a9a522909] check-in: [fe2cbe0021] user: js, branch: trunk, size: 5431 [annotate] [blame] [check-ins using] [diff]

This also renames ObjFW-RT to ObjFW_RT, as hyphens should not be in
framework names. file: [04b4a50718] check-in: [0f42b0eafd] user: js, branch: trunk, size: 5466 [annotate] [blame] [check-ins using] [diff]

A glue library is required as the compiler generates direct references
to some runtime functions. file: [90367d03a6] check-in: [d5706b7070] user: js, branch: trunk, size: 5443 [annotate] [blame] [check-ins using] [diff]

This allows opening and closing the library, but does not do all the
initialization yet and does not export any functions. file: [ba7732f086] check-in: [0d6873e122] user: js, branch: trunk, size: 3747 [annotate] [blame] [check-ins using]
