Describe the solution you'd like
General scrub of users guide

• Replace non-documented formatting mechanisms for return codes (causes errors)
  • Custom table aliases for return values causing issues, use built in
• Make references into links where needed
• Fix links where needed (remove private links)
• Remove duplicated documentation in *.c files (API's documented in *.h, with prototype)
• Remove duplicated brief in API table (pull from object brief)
• Remove xrefitem style formatting (caused warnings, see Remove old ASIST mnemonics from doxygen comments #553)
• Fix glossary table
• Fix use of BSP where PSP applies
• Performance collection focused on cFE, not tool (updated reference for java tool)
• Update Event Message Format documentation to match order/contents
• Update applicable documents with modern references
• Removed no-longer-up-to-date dox templates (eclipse header templates)
• Cleaned up SB sequence counter section
• Added a couple FAQs
• Single sourced the versioning section
• Resolved ALL doxygen warnings (including those detailed in doxygen warning expected <TR> tag and illegal command #403)

Describe alternatives you've considered
None

Additional context
Related issues: #212, #261, #267, #389, #403, #499, #506, #508, #531, #536
Looks like EDS file for SB needs GetPipeIdByNameErrorCounter

Future considerations

• scrub return codes, not all listed in current API documentation
• remove autodoc, explicitly document (futureproof from missing documentation)
