Updates for BFD mibs.
Added checks for printing variables with wrong types.

When -OQ command line argument is used, variable formatter preffers the type
of the varible parsed from a MIB file instead of checking type of the variable
as parsed from SNMP message.

This can lead to crashes when incoming packets contains a variable with
NULL type, while the MIB says the variable should be non-NULL, like Integer.
The formatter then tries to interpret the NULL (from packet) as Integer (from
MIB file).
Added test for sprint_realloc_variable with -OQ cmdline argument.

When enlarging a large_fd_set, use FD_ZERO if possible

The most common case of creating a large_fd_set on UNIX
is to create it with size zero, and then immediately enlarge
it to size FD_SETSIZE.  Instead of looping and calling
FD_CLR(), we can optimize this common case with the OS's
FD_ZERO.
