Stephen Kitt 1013d4d910 docs: rewrite admin-guide/sysctl/abi.rst
Following the structure used in sysctl/kernel.rst, this updates
abi.rst to use ReStructured Text more fully and updates the entries to
match current kernels:

  * the list of files is now the table of contents;
  * links are used to point to other documentation and other sections;
  * all the existing entries are no longer present, so this removes
    them;
  * document vsyscall32.

Mentions of the kernel version are dropped. Since the document is
entirely rewritten, I've replaced the copyright statement.

------------------------------------------------------------------------------
The files in ``/proc/sys/abi`` can be used to see and modify
ABI-related settings.
Currently, these files might (depending on your configuration)
show up in ``/proc/sys/kernel``:
.. contents:: :local:
vsyscall32 (x86)
================
Determines whether the kernels maps a vDSO page into 32-bit processes;
can be set to 1 to enable, or 0 to disable. Defaults to enabled if
``CONFIG_COMPAT_VDSO`` is set, disabled otherwide.
This controls the same setting as the ``vdso32`` kernel boot
parameter.
