Create local C library implementation (2/2)
- This change is split into two separate patches in order to simplify the history as interpreted by 'git'. The split is between the move/rename and addition of new files. - Remove dependency on toolchain C library headers and functions in order to ensure behavioural compatibility between toolchains. - Use FreeBSD as reference for C library implementation. - Do not let GCC use default library include paths. - Remove unused definitions in modified headers and implementations. - Move C library files to 'lib/stdlib' and 'include/stdlib'. - Break std.c functions out into separate files.

+ * rune_t is declared to be an ``int'' instead of the more natural

+ * ints cannot hold 32 bits, you will be in trouble. The reason an int was
+ * chosen over a long is that the is*() and to*() routines take ints (says
+ * ANSI C), but they use __ct_rune_t instead of int.
+ *
+ * NOTE: rune_t is not covered by ANSI nor other standards, and should not
+ * be instantiated outside of lib/libc/locale. Use wchar_t. wchar_t and
+ * rune_t must be the same type. Also, wint_t must be no narrower than
+ * wchar_t, and should be able to hold all members of the largest
+ * character set plus one extra value (WEOF), and must be at least 16 bits.
