    Linux: Fix USE_UCONTEXT detection
    
    On Linux, afs/param.h determines whether to use the ucontext()
    function based on the glibc version. However, the glibc version
    macros aren't available until a C library header has been included.
    
    There have been a couple of attempts to fix this. The first included
    afs_sysnames.h before the C library check, but this wasn't sufficient
    to pull in a header for all builds. The second included stdio.h before
    including afs/param.h in process.c.
    
    Whilst the second approach works, it has the drawback that it breaks
    our convention that afsconfig.h and afs/param.h must always be the first
    includes in a file. More seriously, it means that the behaviour of
    afs/param.h is different depending on where it appears in the include
    order - which is especially dangerous for 3rd party user.
    
    So, this patch tries to resolve all of this by explicitly including
    features.h before doing the glibc version checks. The only danger I
    can see here is that Linux platforms without glibc may lack a
    features.h, but I suspect we have trouble building on such platforms
    in any case.
