MFC 199805,203532,204329,210063,210065:
- Change gcore in order to get rid of the procfs accesses and use FreeBSD's
  specific sysctls and ptrace interfaces.
  This change switches a bit gcore POLA that is summarized here:
  - now gcore can recognize threads within the process and handle dumps
    on thread-scope
  - the process to be analyzed will be stopped during its gcore run
  - gcore may not work with processes which are actively being analyzed
    by gdb or truss
  - the ptrace interface may cause syscalls to return EINTR, thus
    interferring with signals handling within the process
- Fix gcore so that it can have the '-s' flag without hanging.
- Fix the way the segments are included in the gcore outputs (with the
  default invokation):
  - Right now if segments are not writable are not included. Remove this.
  - Right now if a segment is mapped with NOCORE the check is not honoured.
    Change this by checking the newly added flag, from libutil,
    KVME_FLAG_NOCOREDUMP.

  Besides that, add a new flag (-f) that forces a 'full' dump of all the
  segments excluding just the malformed ones. This might be used very
  carefully as, among the reported segments, there could be memory
  mapped areas that could be vital to program execution.

Add the ability for GDB to printout the thread name along with other thread
specific informations.
In order to achieve that, for both on-line debugging and core analysis,
a new member to PT_LWPINFO ptrace(2) interface is added and a new
ELF note (NT_THRMISC) as well.

SVN rev 215679 on 2010-11-22 14:42:13Z by attilio

Add the ability for GDB to printout the thread name along with other
thread specific informations.

In order to do that, and in order to avoid KBI breakage with existing
infrastructure the following semantic is implemented:
- For live programs, a new member to the PT_LWPINFO is added (pl_tdname)
- For cores, a new ELF note is added (NT_THRMISC) that can be used for
  storing thread specific, miscellaneous, informations. Right now it is
  just popluated with a thread name.

GDB, then, retrieves the correct informations from the corefile via the
BFD interface, as it groks the ELF notes and create appropriate
pseudo-sections.

suitable for copying with sysctl/ptrace interface </janitor task>.

Make gcore(1) 64 bit safe.  It was trying to parse the /proc/*/map file
using sscanf and truncating the start/end entries by writing them with a
32 bit int descriptor (%x).  The upper bytes of the 64 bit vm_offset_t
variables (for little endian machines) were uninitialized.  For big endian
machines, things would have been worse because it was storing the 32 bit
value in the upper half of the 64 bit variable.  I've changed it to use
%lx and long types.  That should work on all our platforms.

The actual changes were:

elfcore.c 1.11:
Use a uintmax_t 'cos we con't know if php->p_filesz will be a
Elf32_Size or an Elf64_Size and we don't know how these relate to
size_t. Change some ints to size_t and ssize_ts.

gcore.c 1.28:
Include <arpa/inet.h> for ntohl, which is used in N_BADMAG.
Use a uid_t for a uid.

md-nop.c 1.6:
Mark some parameters as unused.

MFC: * Most of existing include/elf.h is in elf-hints.h.
       elf.h is now a compatibility header with Solaris/SVR4.
	 * Consumers of elf.h now use the minimalist elf header possible.

This change is motivated by Binutils 2.11 and too much clashing over
our base elf headers and the Binutils elf headers.

Change our ELF binary branding to something more acceptable to the Binutils
maintainers.

After we established our branding method of writing upto 8 characters of
the OS name into the ELF header in the padding; the Binutils maintainers
and/or SCO (as USL) decided that instead the ELF header should grow two new
fields -- EI_OSABI and EI_ABIVERSION.  Each of these are an 8-bit unsigned
integer.  SCO has assigned official values for the EI_OSABI field.  In
addition to this, the Binutils maintainers and NetBSD decided that a better
ELF branding method was to include ABI information in a ".note" ELF
section.

With this set of changes, we will now create ELF binaries branded using
both "official" methods.  Due to the complexity of adding a section to a
binary, binaries branded with ``brandelf'' will only brand using the
EI_OSABI method.  Also due to the complexity of pulling a section out of an
ELF file vs. poking around in the ELF header, our image activator only
looks at the EI_OSABI header field.

Note that a new kernel can still properly load old binaries except for
Linux static binaries branded in our old method.

  *
  * For a short period of time, ``ld'' will also brand ELF binaries
  * using our old method.  This is so people can still use kernel.old
  * with a new world.  This support will be removed before 5.0-RELEASE,
  * and may not last anywhere upto the actual release.  My expiration
  * time for this is about 6mo.
  *

useracc() the prequel:

Merge the contents (less some trivial bordering the silly comments)
of <vm/vm_prot.h> and <vm/vm_inherit.h> into <vm/vm.h>.  This puts
the #defines for the vm_inherit_t and vm_prot_t types next to their
typedefs.

This paves the road for the commit to follow shortly: change
useracc() to use VM_PROT_{READ|WRITE} rather than B_{READ|WRITE}
as argument.

Make gcore work again.  It was broken by a format change in the
procfs map file when object IDs were eliminated in the mega-commit
that included procfs_map.c revision 1.19.

The map file is a terrible hodge-podge.  The fields that are used
mainly for kernel debugging should be moved out of it into a
separate file, so that the interface presented by the map file to
applications can remain stable in the face of VM system changes.
