Evgeniy Reizner b618e0ae13 Remove non-breaking spaces from comments. 
`0xC2A0` was used, for some reasons. It's not really a problem, but Qt Creator
constatly trying to replace them with regular spaces, so I have to edit those
files separately.

Evgeniy Reizner 780d640c02 Remove unnecessary check in hb_buffer_t::set_masks.

David Corbett a03f5f4dfb Replace "ISO 639" with "BCP 47" 
`hb_language_from_string` accepts not only ISO 639 but also BCP 47. Not
all ISO 639 codes are valid BCP 47 tags but the function does not accept
overlong language subtags anyway.

Behdad Esfahbod 606bf57430 Revert forcing use of single-parameter static_assert() 
Some clang versions define static_assert as a macro apparently, so we cannot
redefine it...

This reverts commit 94bfea0ce6.

Behdad Esfahbod f0ef096b8c Don't add reference in get_unicode_funcs() functions 
Users don't expect a new reference returned from a get() function.
Indeed, all users of that API I foud where NOT destroying the reference.
Just change the implementations to NOT return a reference.

This applies to the following APIs:
hb_unicode_funcs_get_default()
hb_glib_get_unicode_funcs()
hb_icu_get_unicode_funcs()
