[auth-rsa.c channels.c jpake.c key.c misc.c misc.h monitor.c]
     [packet.c ssh-rsa.c]
     implement a timing_safe_cmp() function to compare memory without leaking
     timing information by short-circuiting like memcmp() and use it for
     some of the more sensitive comparisons (though nothing high-value was
     readily attackable anyway); "looks ok" markus@

     introduce xcalloc() and xasprintf() failure-checked allocations
     functions and use them throughout openssh

     xcalloc is particularly important because malloc(nmemb * size) is a
     dangerous idiom (subject to integer overflow) and it is time for it
     to die

     remove IV support from the CRC attack detector, OpenSSH has never used
     it - it only applied to IDEA-CFB, which we don't support.
     prompted by NetBSD Coverity report via elad AT netbsd.org;
