Add yr_get_version to report the version of the library loaded at runtime (#2247)

Browse Source 
YR_MAJOR_VERSION, YR_MINOR_VERSION and YR_MICRO_VERSION are fixed when the
caller is compiled, so a program linked against a shared libyara has no way
to tell which version it actually loaded. Distros ship libyara.so in its own
package precisely so it can be updated independently of its consumers, which
is exactly the case the macros cannot describe.

Add yr_get_version(), which reports the version of the library that is
actually loaded. Any argument may be NULL if the caller does not need that
component, and since the function touches no global state it can be called
before yr_initialize.

Closes #2136
