Move shared headers in common/include

Browse Source 
Headers that will be shared between old includes and NetBSD-like includes
are moved into common/include tree. They are still copied in /usr/include
in 'make includes', so compilation and programs aren't be affected.

/* The <minix/ansi.h> header attempts to decide whether the compiler has enough
* conformance to Standard C for Minix to take advantage of. If so, the
* symbol _ANSI is defined (as 31459). Otherwise _ANSI is not defined
* here, but it may be defined by applications that want to bend the rules.
* The magic number in the definition is to inhibit unnecessary bending
* of the rules. (For consistency with the new '#ifdef _ANSI" tests in
* the headers, _ANSI should really be defined as nothing, but that would
* break many library routines that use "#if _ANSI".)
* If _ANSI ends up being defined, a macro
*
* _PROTOTYPE(function, params)
*
* is defined. This macro expands in different ways, generating either
* ANSI Standard C prototypes or old-style K&R (Kernighan & Ritchie)
* prototypes, as needed. Finally, some programs use _CONST, _VOIDSTAR etc
* in such a way that they are portable over both ANSI and K&R compilers.
* The appropriate macros are defined here.
