Mark static modules with a different type, and check that type at unload. Only call unload low level implementation if type is dynamic.
Add flags to indicate symbol visibility for OS_ModuleLoad(). By default (flags=0) symbols will have global visibility, which should be the same as existing behavior.
This restores the original behavior when using OS_SymbolLookup on POSIX, so it doesn't return OS_ERR_NOT_IMPLEMENTED. This is required for transitional purposes. Will submit a separate bug about use platform-dependent logic here.

Add doxygen comment for flags parameter on OS_ModuleLoad Also correct the capitalization of parameters to the OS_ModuleSymbolLookup which caused them to be reported as undocumented.

Doxygen issue is fixed on commit 3f5e8f3 (the force earlier was to just to revert an incomplete fix that I pushed too soon - its all good now). |

Rather than CFE generating an osconfig.h file directly, it just needs to select file(s) from the defs directory and pass them to OSAL for the config.

Describe the contribution
Fix #637, static module unload fix
Fix #641, add flags to OS_ModuleLoad
Testing performed
Bundle CI on astrogeco: https://travis-ci.com/github/astrogeco/cFS/builds/201769124
Expected behavior changes
PR #638 - Ensure that the handle is not NULL before invoking dlclose(). In particular the handle will be NULL for static modules. Shutdown after CTRL+C occurs normally (no segfault).
PR #643 - Add a "flags" parameter to OS_ModuleLoad() to indicate the desired symbol visibility:
CFE should use LOCAL flag for apps, and GLOBAL flags for libraries.
