parsing and comparions by programs. The LIBSSH2_VERSION_NUM define will
always follow this syntax:
0xXXYYZZ
Where XX, YY and ZZ are the main version, release and patch numbers in
hexadecimal (using 8 bits each). All three numbers are always represented
using two digits. 1.2 would appear as "0x010200" while version 9.11.7
appears as "0x090b07".
This 6-digit (24 bits) hexadecimal number does not show pre-release number,
and it is always a greater number in a more recent release. It makes
comparisons with greater than and less than work.
