header file fixes: multiple include guard consistency and correctness one file was reusing another file's macro name, and many had inconsistent underscores and application of SYS prefix, etc. patch by Szabolcs Nagy (nsz)

don't claim support for resolv.h APIs that aren't supported the value 19991006 for __RES implies availability of res_ninit and related functions that take a resolver state argument; these are not supported since our resolver is stateless. instead claim support for just the older API by defining __RES to 19960801. based on patch by Dmitrij D. Czarkoff.

fix res_mkquery and res_send prototypes in resolv.h historically these functions appeared in BSD 4.3 without prototypes, then in the bind project prototypes were added to resolv.h, but those were incompatible with the definitions of the implementation. the bind resolv.h became the defacto api most systems use now, but the old internal definitions found their way into the linux manuals and thus into musl.

int dn_comp(const char *, unsigned char *, int, unsigned char **, unsigned char **);
de-duplicate dn_expand, fix return value and signature, clean up the duplicate code in dn_expand and its incorrect return values are both results of the history of the code: the version in __dns.c was originally written with no awareness of the legacy resolver API, and was later copy-and-paste duplicated to provide the legacy API. this commit is the first of a series that will restructure the internal dns code to share as much code as possible with the legacy resolver API functions. I have also removed the loop detection logic, since the output buffer length limit naturally prevents loops. in order to avoid long runtime when encountering a loop if the caller provided a ridiculously long buffer, the caller-provided length is clamped at the maximum dns name length.
