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

With this change the yr_scanner_scan_mem_blocks function can return ERROR_BLOCK_NOT_READY when the YR_MEMORY_BLOCK_ITERATOR that provides memory blocks to the function is not ready to return the next block. After this error the caller can retry the call to yr_scanner_scan_mem_blocks multiple times until the function succeeds or fails with some other error code.
