[PATCH 1/12] bug fix: openssh-4.3p2 memory leak

[Kylene Jo Hall]

The variable cmd is xmalloc'd by buffer_get_string.  It is then used in
some places but never freed.  This patch places the xfree after the last
usage and within the confines of all paths.  This entire set of patches
passed the regression tests on my system.  Memory leak bug found by
Coverity.
