While the main goal for kernel-doc is to be used inside the Linux
Kernel, other open source projects could benefit for it. That's
currently the case of QEMU, which has a fork, mainly due to two
reasons:
- they need an extra C function transform rule;
- they handle the html output a little bit different.
Add an extra optional argument to make easier for the code to be
shared, as, with that, QEMU can just create a new derivated class
that will contain its specific rulesets, and just copy the
remaining kernel-doc files as-is.

Drop context analysis and lock (tracking) attributes to avoid
kernel-doc warnings.
There are now lots of warnings like these:
Documentation/core-api/kref:328: ../include/linux/kref.h:72: WARNING: Invalid C declaration: Expected end of definition. [error at 96]
int kref_put_mutex (struct kref *kref, void (*release)(struct kref *kref), struct mutex *mutex) __cond_acquires(true# mutex)
------------------------------------------------------------------------------------------------^
Documentation/core-api/kref:328: ../include/linux/kref.h:94: WARNING: Invalid C declaration: Expected end of definition. [error at 92]
int kref_put_lock (struct kref *kref, void (*release)(struct kref *kref), spinlock_t *lock) __cond_acquires(true# lock)
--------------------------------------------------------------------------------------------^
The regex is suggested by Mauro; mine was too greedy. Thanks.
Updated context analysis and lock macros list provided by PeterZ. Thanks.

Over the time, most of the changes at kernel-doc are related
to maintaining a list of transforms to convert macros into pure
C code.
Place such transforms on a separate module, to cleanup the
parser module.
There is an advantage on that: QEMU also uses our own kernel-doc,
but the xforms list there is different. By placing it on a
separate module, we can minimize the differences and make it
easier to keep QEMU in sync with Kernel upstream.
No functional changes.

Mangling with #defines is not nice, as we may end removing
the macro names, preventing several macros from being properly
documented.
Also, on defines, we have something like:
#define foo(a1, a2, a3, ...) \
/* some real implementation */
The prototype part (first line on this example) won't contain
any macros, so no need to apply any regexes on it.
With that, move the apply_transforms() logic to ensure that
it will be called only on functions.
