Rename ca keyboard to ca-fr

"ca" will shortly be used for the Canadian Multilingual keyboard.
Expand the elf brandelf infrastructure to give access to the whole ELF
header (Elf_Ehdr) to determine if a particular interpretor wants to
accept it or not. Use this mechanism to filter EABI arm on OABI arm
kernels, and vice versa. This method could also be used to implement
OABI on EABI arm kernels, if desired, or to allow a single mips kernel
to run o32, n32 and n64 binaries.

/usr/libexec/ld.so.1 never was a thing on FreeBSD/arm. This was the
FreeBSD 3.x and 4.x run time linker. FreeBSD/arm's first release was
5.0. Retire this long-dead code.

Import the tools used to convert the keymap files from SYSCONS (in locale
dependent encoding) to NEWCONS (Unicode).

The file "LANG.map" is used to convert INDEX.keymaps. It has 3 columns:
- the language ID as used in the source file
- the language ID to be used in the generated file (e.g. "iw" -> "he")
- the encoding of the menu texts for this language
The conversion result is written to STDOUT.

The file "KBDFILES.map" is used to batch convert keymap files. It's
columns are:
- the encoding used for the keymap sounce file
- the name of the source file
- the name of the generated file
The output files are created in the TEMP sub-directory of the vt keymap
directory, in order to preserve (possibly uncommitted) keymap files in
/usr/src/share/vt/keymaps.

The convert-keymap.pl script can be directly executed by passing the
source file name and the encoding on the command line. It writes to
STDOUT and generates hex Unicode codepoints by default. (This can be
changed to decimal in the script.)

While written for the one-time conversion of the SYSCONS keymaps into
the format required for NEWCONS, I think these tools may be useful for
easy conversion of possible further SYSCONS keymap files, that have not
been committed to the source tree.

Use the "bSubslotSize" and "bSubFrameSize" fields to obtain the actual
sample size. According to the USB audio frame format specification
from USB.org, the value in the "bBitResolution" field can be less than
the actual sample size, depending on the actual hardware, and should
not be used for this computation.

  [PowerPC] 32-bit ELF PIC support

  This adds initial support for PPC32 ELF PIC (Position Independent Code; the
  -fPIC variety), thus rectifying a long-standing deficiency in the PowerPC
  backend.

There exists a possible sequence of page table page allocation failures
starting with a superpage demotion by pmap_enter() that could result in
a PV list lock being held when pmap_enter() is just about to return
KERN_RESOURCE_SHORTAGE.  Consequently, the KASSERT that no PV list locks
are held needs to be replaced with a conditional unlock.
