Fix nasa#821, add accessor functions for version strings
Browse files Browse the repository at this point in the history
Adds 4 version API calls:

const char *OS_GetVersionString(void);
const char *OS_GetVersionCodeName(void);
void OS_GetVersionNumber(uint8[4]);
uint32 OS_GetBuildNumber(void);

These return the values of current macros in osapi-version.h.

The accessor function should be the preferred way to get the OSAL version
info (vs. using macro directly) as it is evaluated at OSAL library
compile time, rather than application compile time, and thus will
remain correct in the event that OSAL is relinked without recompiling
the application.
