66a605b22a libc: provide fputc_unlocked
Among the same justification as the other stdio _unlocked; in addition to an
inline version in <stdio.h>, we must provide a function in libc as well for
the functionality. This fixes the lang/gcc* builds, which want to use the
symbol from libc.

a508eb379b stdio: provide _unlocked variants of fflush, fputc, fputs, fread, fwrite
fflush_unlocked is currently desired in ports by sysutils/metalog, and
redefined as the locked fflush.

fputc_unlocked, fputs_unlocked, fread_unlocked, and fwrite_unlocked are
currently desired in ports by devel/elfutils, and redefined as the locked
fputs, fread, and fwrite respectively.

878fd59d87 libc: remove gets
gets is unsafe and shouldn't be used (for many years now).  Leave it in
the existing symbol version so anything that previously linked aginst it
still runs, but do not allow new software to link against it.

(The compatability/legacy implementation must not be static so that
the symbol and in particular the compat sym gets@FBSD_1.0 make it
into libc.)

6b22553e16 include: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Replace uses of the GCC __nonnull__ attribute with the clang nullability

the new qualifiers will produce the same warnings and will be useful for
static checkers but will not cause aggressive optimizations.

GCC will not produce such warnings and developers will have to use
upgraded GCC ports built with the system headers from r312538.

e925cab0ee tools/build looks for _WITH_GETLINE in /usr/include/stdio.h to see if
we need to include it in -legacy or not. Since the ifdef was removed,
this broke building 10.x and older source trees on -current. Restore
just enough of _WITH_GETLINE to allow these older source trees to
still build and properly omit getline() from their -legacy library.

31330e2843 stdio.h: Fix function-type typedef style and use _types.h __ssize_t
I'm still not sure why only Pypy runs into the error with the function
typedefs.  Fix it anyway.

Use __ssize_t instead of ssize_t for the types; it's possible for the size_t
type to not be visible if at the wrong POSIX_VISIBLE level.

ab875ea726 Next stage of stdio cleanup: Retire __sFILEX and merge the fields back into
__sFILE.  This was supposed to be done in 6.0.  Some notes:
- Where possible I restored the various lines to their pre-__sFILEX state.
- Retire INITEXTRA() and just initialize the wchar bits (orientation and
  mbstate) explicitly instead.  The various places that used INITEXTRA
  didn't need the locking fields or _up initialized.  (Some places needed
  _up to exist and not be off the end of a NULL or garbage pointer, but
  they didn't require it to be initialized to a specific value.)
- For now, stdio.h "knows" that pthread_t is a 'struct pthread *' to
  avoid namespace pollution of including all the pthread types in stdio.h.
  Once we remove all the inlines and make __sFILE private it can go back
  to using pthread_t, etc.
- This does not remove any of the inlines currently and does not change
  any of the public ABI of 'FILE'.
