secilc/docs: Convert DocBook documentation into github markdown Converting to github markdown allows for easier integration with the SELinux project wiki and viewing of documentation directly on github without creating PDFs or reading through DocBook XML. The conversion of DocBook to github markdown would not format tables or keyword links properly. By maintaining the documentation in github markdown in the repository, the content is well formatted with a table of contents when viewing in the github wiki or in the repository. The migration from DocBook to github markdown was done using Pandoc and manual fixups. Mappings of CIL keywords to headings that were lost in the DocBook conversion were added back. An introduction and design philosphy was also pulled from the SELinux project wiki to provide more cohesion to the current documentation. Running make will now convert the github markdown into PDF and HTML. Signed-off-by: Yuli Khodorkovskiy <ykhodorkovskiy@tresys.com>

Network Labeling Statements
===========================
ipaddr
------
Declares a named IP address in IPv4 or IPv6 format that may be referenced by other CIL statements (i.e. [`netifcon`](cil_network_labeling_statements.md#netifcon)).
Notes:
- CIL statements utilising an IP address may reference a named IP address or use an anonymous address, the examples will show each option.
- IP Addresses may be declared without a previous declaration by enclosing within parentheses e.g. `(127.0.0.1)` or `(::1)`.
**Statement definition:**
secilc/docs: use fenced code blocks for cil examples Also fixes the occasional missing brackets as higlighted by my editor, however the individual examples where not reviewed much closer. secilc was chosen as language name because the compiler is named secilc and outside of SELinux the name cil is less searchable and could lead to confusion.

secilc/docs: Convert DocBook documentation into github markdown Converting to github markdown allows for easier integration with the SELinux project wiki and viewing of documentation directly on github without creating PDFs or reading through DocBook XML. The conversion of DocBook to github markdown would not format tables or keyword links properly. By maintaining the documentation in github markdown in the repository, the content is well formatted with a table of contents when viewing in the github wiki or in the repository. The migration from DocBook to github markdown was done using Pandoc and manual fixups. Mappings of CIL keywords to headings that were lost in the DocBook conversion were added back.
