Elliott Hughes 0f461e35f6 Fix <sys/resource.h>. 
The situation here is a bit confusing. On 64-bit, rlimit and rlimit64 are
the same, and so getrlimit/getrlimit64, setrlimit/setrlimit64,
and prlimit/prlimit64 are all the same. On 32-bit, rlimit and rlimit64 are
different. 32-bit architectures other than MIPS go one step further by having
an even more limited getrlimit system call, so arm and x86 need to use
ugetrlimit instead of getrlimit. Worse, the 32-bit architectures don't have
64-bit getrlimit- and setrlimit-equivalent system calls, and you have to use
prlimit64 instead. There's no 32-bit prlimit system call, so there's no
easy implementation of that --- what should we do if the result of prlimit64
won't fit in a struct rlimit? Since 32-bit survived without prlimit/prlimit64
for this long, I'm not going to bother implementing prlimit for 32-bit.

We need the rlimit64 functions to be able to build strace 4.8 out of the box.

# This file is used to automatically generate bionic's system call stubs.
#
# Each non-blank, non-comment line has the following format:
#
# return_type func_name[|alias_list][:syscall_name[:socketcall_id]]([parameter_list]) arch_list
#
# where:
# arch_list ::= "all" | arch+
# arch ::= "aarch64" | "arm" | "mips" | "x86" | "x86_64"
#
# Note:
# - syscall_name corresponds to the name of the syscall, which may differ from
# the exported function name (example: the exit syscall is implemented by the _exit()
# function, which is not the same as the standard C exit() function which calls it)
#
# - alias_list is optional comma separated list of function aliases.
#
# - The call_id parameter, given that func_name and syscall_name have
# been provided, allows the user to specify dispatch style syscalls.
# For example, socket() syscall on i386 actually becomes:
# socketcall(__NR_socket, 1, *(rest of args on stack)).
#
# - Each parameter type is assumed to be stored in 32 bits.
#
# This file is processed by a python script named gensyscalls.py.
