docs/system: convert Texinfo documentation to rST

Apart from targets.rst, which was written by hand, this is an automated
conversion obtained with the following command:

  makeinfo --force -o - --docbook \
    -D 'qemu_system_x86 QEMU_SYSTEM_X86_MACRO' \
    -D 'qemu_system     QEMU_SYSTEM_MACRO' \
    $texi | pandoc -f docbook -t rst+smart | perl -e '
      $/=undef;
      $_ = <>;
      s/^-  − /-  /gm;
      s/QEMU_SYSTEM_MACRO/|qemu_system|/g;
      s/QEMU_SYSTEM_X86_MACRO/|qemu_system_x86|/g;
      s/(?=::\n\n +\|qemu)/.. parsed-literal/g;
      s/:\n\n::$/::/gm;
      print' > $rst

In addition, the following changes were made manually:

- target-i386.rst and target-mips.rst: replace CPU model documentation with
  an include directive

- monitor.rst: replace the command section with a comment

- images.rst: add toctree

- target-arm.rst: Replace use of :math: (which Sphinx complains
  about) with :sup:, and hide it behind |I2C| and |I2C| substitutions.

Content that is not @included remains exclusive to qemu-doc.texi.

[PMM: Fixed target-arm.rst use of :math:; remove out of date
 note about images.rst from commit message; fixed expansion
 of |qemu_system_x86|; use parsed-literal in invocation.rst
 when we want to use |qemu_system_x86|; fix incorrect subsection
 level for "OS requirements" in target-i386.rst; fix incorrect
 syntax for making links to other sections of the manual]

+Sparc64 System emulator
+-----------------------
+
+Use the executable ``qemu-system-sparc64`` to simulate a Sun4u
+(UltraSPARC PC-like machine), Sun4v (T1 PC-like machine), or generic
+Niagara (T1) machine. The Sun4u emulator is mostly complete, being able
+to run Linux, NetBSD and OpenBSD in headless (-nographic) mode. The
+Sun4v emulator is still a work in progress.
+
+The Niagara T1 emulator makes use of firmware and OS binaries supplied
+in the S10image/ directory of the OpenSPARC T1 project
+http://download.oracle.com/technetwork/systems/opensparc/OpenSPARCT1_Arch.1.5.tar.bz2
+and is able to boot the disk.s10hw2 Solaris image.
+
+::
+
+   qemu-system-sparc64 -M niagara -L /path-to/S10image/ \
+                       -nographic -m 256 \
+                       -drive if=pflash,readonly=on,file=/S10image/disk.s10hw2
+
+QEMU emulates the following peripherals:
+
+-  UltraSparc IIi APB PCI Bridge
+
+-  PCI VGA compatible card with VESA Bochs Extensions
+
+-  PS/2 mouse and keyboard
+
+-  Non Volatile RAM M48T59
+
+-  PC-compatible serial ports
+
+-  2 PCI IDE interfaces with hard disk and CD-ROM support
+
+-  Floppy disk
+
+The following options are specific to the Sparc64 emulation:
+
+``-prom-env string``
+   Set OpenBIOS variables in NVRAM, for example:
+
+   ::
+
+      qemu-system-sparc64 -prom-env 'auto-boot?=false'
+
+``-M [sun4u|sun4v|niagara]``
+   Set the emulated machine type. The default is sun4u.
