Description: Limit number of file descriptors used for select() to FD_SETSIZE.

 The GETDTABLESIZE macro is used to determine the maximum file

 descriptor that can be used with select().  On Linux, the upper limit

 on newly-opened file descriptors (returned, equivalently, by either

 sysconf(_SC_OPEN_MAX), getrlimit(RLIMIT_FSIZE), or getdtablesize())

 is variable, and may be greater than the size of the 'fd_set'

 structure.  In particular, systemd apparently sets the limit to 65536

 by default, whereas glibc's 'fd_set' is only 1024 bits.  Thus, the

 macro should return either the upper limit returned by

 getdtablesize(), or the constant FD_SETSIZE, whichever is smaller.
