Warner Losh 86d99b6884 Remove EISA bus support for add-in cards. Remove related kernel and
compile options. Remove doxygen pointers to now deleted files. Remove
EISA and VME as examples in bus_space.9.

Retained EISA mode code for IO PIC and MPTABLES because that's not
EISA bus, per se, and some people have abused EISA to mean "EISA-like
behavior as opposed to ISA" rather than using it for EISA add-in
cards.

       The kernel subsystem API documentation generation framework.
      --------------------------------------------------------------

For every Doxyfile-(.*) the Makefile adds the public targets $1, pdf-$1 and
clean-$1. For e.g. Doxyfile-dev_pci this translates to the targets dev_pci,
pdf-dev_pci and clean-dev_pci.

Additionally, the targets 'all', 'pdf-all' and 'clean' to generate or remove
the documentation for all targets are available.

The file 'Dependencies' contains dependencies for the .tag files.

To add another part to the documentation just copy a Doxyfile and add
the necessary dependencies to the file 'Dependencies'.

The following environment variables can be used in the Doxyfile:
 - DOXYGEN_SRC_PATH		(/usr/src/sys)
 - DOXYGEN_DEST_PATH		(where the docs are generated)
 - DOXYGEN_TARGET_ARCH		(${TARGET_ARCH} if set, else ${MACHINE_ARCH})

For the PDF generation you may have to change some limits in the latex
configuration (the build may fail and an error about e.g. "pool size" is
shown), for print/teTeX this is done in
	/usr/local/share/texmf/web2c/texmf.cnf

Programs needed to generate the API docs:
 - devel/doxygen
 - print/teTeX
 - graphics/graphviz
