Presently sys/sysmacros.h is entirely defined in sysdeps. This would
mean that the deprecation logic coming up in the next patch would have
to be written twice (in generic/ and unix/sysv/linux/). To avoid that,
hoist all but the unavoidably system-dependent logic to misc/, leaving a
bits/ header behind. This also promotes the Linux-specific encoding of
dev_t, which accommodates 32-bit major and minor numbers in a 64-bit dev_t,
to generic, as glibc's dev_t is always 64 bits wide.
The former Linux implementation used inline functions to avoid evaluating
arguments more than once. After this change, all platforms use inline
functions, which means that three new symbols are added to the generic ABI.
(These symbols are in the user namespace, which is how they have always
been on Linux. They begin with "gnu_dev_", so collisions with user code
are pretty unlikely.)
New ports henceforth need only provide a bits/sysmacros.h defining
internal macros __SYSMACROS_{DECLARE,DEFINE}_{MAJOR,MINOR,MAKEDEV}.
This is only necessary if the kernel encoding is incompatible with
the now-generic encoding (for instance, it would be necessary for
FreeBSD).
While I was at it, I added a basic round-trip test for these functions.
* sysdeps/generic/sys/sysmacros.h: Delete file.
* sysdeps/unix/sysv/linux/makedev.c: Delete file.
* sysdeps/unix/sysv/linux/sys/sysmacros.h: Move file ...
* bits/sysmacros.h: ... here; this encoding is now the generic
encoding. Now defines only the following macros:
__SYSMACROS_DECLARE_MAJOR, __SYSMACROS_DEFINE_MAJOR,
__SYSMACROS_DECLARE_MINOR, __SYSMACROS_DEFINE_MINOR,
__SYSMACROS_DECLARE_MAKEDEV, __SYSMACROS_DEFINE_MAKEDEV.

Add GLIBC_2.25.
The sem_* functions bring in references to tdelete, tfind, tsearch and
twalk. But the t* functions are XSI-shaded, while sem_* aren't. This
patch fixes this by using __t* instead, exporting those functions from
libc at version GLIBC_PRIVATE (since sem_* are in libpthread) and
using libc_hidden_* for the benefit of calls within libc.
Tested for x86_64 and x86 (testsuite, and comparison of disassembly of
installed stripped shared libraries). libpthread gets changes from
PLT reordering; addresses in libc change because of PLT / dynamic
symbol table changes.
