Alejandro Colomar 6f2b277e6d Add mappings for itimerspec

Alejandro Colomar 3bb4e2dc8d Add mappings for getopt(3) and opt{arg,err,ind,opt} 
Glibc also provides them in <getopt.h>, but let's recommend the
portable POSIX header only.

Alejandro Colomar ec625ea9db Add mappings for 'MAP_POPULATE' 
It's not in POSIX, so I found it experimentally.

$ grepc -k MAP_POPULATE
./asm-generic/mman-common.h:26:#define MAP_POPULATE		0x008000	/* populate (prefault) pagetables */
./x86_64-linux-gnu/bits/mman-map-flags-generic.h:34:# define MAP_POPULATE	0x08000		/* Populate (prefault) pagetables.  */

$ grep -r '<bits/mman-map-flags-generic.h>'
x86_64-linux-gnu/bits/mman.h:#include <bits/mman-map-flags-generic.h>
x86_64-linux-gnu/bits/mman-map-flags-generic.h:# error "Never use <bits/mman-map-flags-generic.h> directly; include <sys/mman.h> instead."

So glibc defines it in <sys/mman.h>.

$ grep -r '<asm-generic/mman-common.h>'
asm-generic/mman.h:#include <asm-generic/mman-common.h>
$ grep -r '<asm-generic/mman.h>'
x86_64-linux-gnu/asm/mman.h:#include <asm-generic/mman.h>
$ grep -r '<asm/mman.h>'
linux/mman.h:#include <asm/mman.h>

And the kernel in <linux/mman.h>.

Alejandro Colomar a7d6088546 Add mappings for 'MAXHOSTNAMELEN' 
I couldn't find an documentation about where it should be defined
(POSIX doesn't define it), so my best guess was to find the
definitions experimentally.  Combining my findings in the glibc
repo with the findings in my own Debian system, and ignoring
kernel headers and unrelated headers such as X11's, this is my
best guess.

See:

alx@asus5775:/usr/include$ grepc -k MAXHOSTNAMELEN
./X11/Xtrans/Xtranssock.c:225:#define MAXHOSTNAMELEN 255
./asm-generic/param.h:17:#define MAXHOSTNAMELEN	64	/* max length of hostname */
./protocols/timed.h:44:#define MAXHOSTNAMELEN	64
./x86_64-linux-gnu/ruby-3.0.0/rb_mjit_min_header-3.0.4.h:24134:#define MAXHOSTNAMELEN 64
./x86_64-linux-gnu/sys/param.h:54:# define MAXHOSTNAMELEN	HOST_NAME_MAX

alx@asus5775:~/src/gnu/glibc$ grepc -kx '\.h$' MAXHOSTNAMELEN
./inet/protocols/timed.h:44:#define MAXHOSTNAMELEN	64
./misc/sys/param.h:54:# define MAXHOSTNAMELEN	HOST_NAME_MAX
./sunrpc/rpc/types.h:102:#define        MAXHOSTNAMELEN  64

Omar Sandoval 44480a2de0 Add export from <stdint.h> to <inttypes.h> 
IWYU currently warns for this example:

  $ cat test.c
  #include <inttypes.h>
  #include <stdio.h>

  int main(void)
  {
          uint64_t x = UINT64_C(1234);
          printf("%" PRIu64 "\n", x);
          return 0;
  }
  $ include-what-you-use test.c

  test.c should add these lines:
  #include <stdint.h>    // for UINT64_C, uint64_t

  test.c should remove these lines:

  The full include-list for test.c:
  #include <inttypes.h>  // for PRIu64
  #include <stdint.h>    // for UINT64_C, uint64_t
  #include <stdio.h>     // for printf
  ---

However, the C standard states that "the header <inttypes.h> includes
the header <stdint.h>". So, this program shouldn't need to include
<stdint.h>.

Some mappings were previously added for individual symbols from
<stdint.h> (e.g., commit 24f9fdf0af ("Add more mappings for
[u]intptr_t"), but it's more accurate to export everything. Get rid of
the symbol mappings and add an include mapping.
