    Improve and fix catch-syscall.exp
    
    While fixing another bug, I found that the current
    gdb.base/catch-syscall.exp is kind of messy, could use some
    improvements, and is not correctly testing some things.
    
    I've made the following patch to address all the issues I found.  On the
    organization side, it does a cleanup and removes unecessary imports of
    gdb_prompt, uses prepare_for_testing and clean_restart where needed, and
    fixes some comments.  The testcase was also not correctly testing
    catching syscalls using only numbers, or catching many syscalls at
    once.  I fixed that.
    
    The patch also uses a new method for obtaining the syscalls numbers: it
    relies on the C source file to get them, via <sys/syscall.h> and SYS_*
    macros.  This makes the .exp file simpler because there is no need to
    include target conditionals there.
    
    I tested this on x86_64 Fedora 18.

    	(check_continue, insert_catch_syscall_with_arg): Remove global
    	gdb_prompt.
    	(insert_catch_syscall_with_many_args): Likewise.  Add global
    	decimal.  Fix $filter_str.  Improve testing regex.
    	(check_for_program_end): Remove global gdb_prompt.
    	(test_catch_syscall_without_args): Likewise.  Add global decimal.
    	Improve testing regex.
    	(test_catch_syscall_with_args, test_catch_syscall_with_many_args)

    	to be caught.
    	(test_catch_syscall_with_args_noxml): Remove global gdb_prompt.
    	Add global all_syscalls_numbers.  Test each syscall number to be
    	caught, instead of only testing "close".
