master 756373a772: Fix warnings without XCB or XFixes

[Po Lu]

branch: master
commit 756373a772c2c096bad1b26d7e46fa6144086ce1
Author: Po Lu <luangruo@yahoo.com>
Commit: Po Lu <luangruo@yahoo.com>

    Fix warnings without XCB or XFixes
    
    * src/xterm.c (x_term_init): Don't USE_SAFE_ALLOCA or call
    SAFE_FREE outside of where it is actually used.  For some reason
    the compiler still emitted warnings despite the ((void)
    SAFE_ALLOCA (0)) statement.
