SERVER-9434 Audit and Normalize Process Exit Codes

- Put all references to ExitCode enumerators under an enum class to namespace
  all the enumerators and avoid polluting the mongo namespace with possible
  naming collisions.
- Added magic-number exit codes to exit_code.h like 50 & 51
  (LauncherMiddleError & LauncherError respectively).
- Reserved a range of exit codes to account for FreeBSD's usage of 64-78.
- Renamed all enums with removal of EXIT_ which could conflict or get confused
  with built-in macros.
- camelCased all ExitCode enum values.
- Added the generic - ExitCode::fail - for returning 1 as failure.
- Added explicit dependency on the exit_code.h header for all files using
  ExitCode's.
- Removed all references to implementation-defined exit codes like EXIT_FAILURE
  and EXIT_SUCCESS.
- Narrowed return values of the shell's undocumented quit() argument to portable
  values within 0-255, 0/ExitCode::clean otherwise.
- Deprecated 8 unused ExitCode's
  - java
  - oomMalloc
  - oomRealloc
  - fs
  - clockSkew
  - windowsServiceStop
  - possibleCorruption
  - test
- Wrapped the 2 Windows-only ExitCode's in #ifdef's
  - ntServiceError
  - windowsServiceStop
