This is more compatible with the various conventions used on various

ObjFW_RT used to be a separate project that followed the BSD style, as
it was written in pure C, while ObjFW's style is based on the BSD style
with changes to make it a better fit for Objective-C. This commit
changes ObjFW_RT to use the same style as ObjFW. file: [eecb74dd6c] check-in: [ef6d69931e] user: js, branch: trunk, size: 10824 [annotate] [blame] [check-ins using] [diff]

This currently uses __saveds on all exported functions for simplicity.
As an optimization, __saveds can be removed from some functions later
after careful verification that no code path starting from that function
accesses any data. file: [18895befa5] check-in: [482698c5be] user: js, branch: trunk, size: 12257 [annotate] [blame] [check-ins using] [diff]

This adds the same workaround for objc_enumerationMutation() as for
objc_exception_throw(). file: [4c021bd0e6] check-in: [dff419362e] user: js, branch: trunk, size: 11091 [annotate] [blame] [check-ins using] [diff]

platform.h is only installed as part of ObjFW, not as part of the
runtime. file: [a5d4a53089] check-in: [972fd1d98d] user: js, branch: trunk, size: 8836 [annotate] [blame] [check-ins using] [diff]

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: [75ca2f1db8] check-in: [fe2cbe0021] user: js, branch: trunk, size: 8834 [annotate] [blame] [check-ins using] [diff]

This also renames ObjFW-RT to ObjFW_RT, as hyphens should not be in
framework names. file: [d5822f4845] check-in: [0f42b0eafd] user: js, branch: trunk, size: 8831 [annotate] [blame] [check-ins using]
