perf tools: Add kmod_path__parse function
Provides united way of parsing kernel module path
into several components.
The new kmod_path__parse function and few defines:
int __kmod_path__parse(struct kmod_path *m, const char *path,
bool alloc_name, bool alloc_ext);
#define kmod_path__parse(__m, __p) __kmod_path__parse(__m, __p, false, false)
#define kmod_path__parse_name(__m, __p) __kmod_path__parse(__m, __p, true , false)
#define kmod_path__parse_ext(__m, __p) __kmod_path__parse(__m, __p, false, true)
parse kernel module @path and updates @m argument like:
@comp - true if @path contains supported compression suffix,
false otherwise
@kmod - true if @path contains '.ko' suffix in right position,
false otherwise
@name - if (@alloc_name && @kmod) is true, it contains strdup-ed base name
of the kernel module without suffixes, otherwise strudup-ed
base name of @path
@ext - if (@alloc_ext && @comp) is true, it contains strdup-ed string
the compression suffix
It returns 0 if there's no strdup error, -ENOMEM otherwise.
