Rainer Orth 44122162ae Remove ioctl-based procfs support on Solaris 
This is the previously mentioned patch to get rid of
unstructured/ioctl-based procfs support in procfs.c.  Given that support
for structured procfs was introduced in Solaris 2.6 back in 1997 and
we're just removing support for Solaris < 10, there's no point in
carrying that baggage (and tons of support for IRIX and OSF/1 as well)
around any longer.

Most of the patch should be straightforward (removing support for
!NEW_PROC_API, non-Solaris OSes and pre-Solaris 10 quirks).

Only a few points need explanations:

* <sys/syscall.h> was already included unconditionally in most places,
  so there's no need to have guards in a few remaining ones.

* configure.host already obsoletes i?86-*-sysv4.2, i?86-*-sysv5, so
  NEW_PROC_API detection for those in configure.ac can go.

* I'm still including <sys/procfs.h> with #define _STRUCTURED_PROC 1.
  Theoretically, it would be better to include <procfs.h> on Solaris
  (which includes that define), but that breaks the build over
  <procfs.h> vs. gdb's "procfs.h", and doesn't exist on Linux.

* I've regenerated syscall_table[] in proc-events.c with a small script
  from Solaris 10, 11.3, 11.4 <sys/syscall.h>, so there should be no
  traces of older Solaris versions and other OSes left.

* prsysent_t and DYNAMIC_SYSCALLS was only used for AIX 5, but AIX
  doesn't use procfs.c any longer, so all related code can go.

The patch was generated with diff -w so one can easier see changes
without being distracted by simple reindentations.

So far, it has only been compiled and smoke-tested on
amd64-pc-solaris2.1[01], sparcv9-sun-solaris2.1[01], and
x86_64-pc-linux-gnu.  Certainly needs more testing (Solaris 11.3
vs. 11.4, 32-bit gdb, testsuite once I've figured out what's wrong on
Solaris 10 etc.), but it's enough to get a first impression how much
cleanup is possible here.
