Elliott Hughes 6660d6c00b Rewrite renameat().
risc-v doesn't have renameat(2), only renameat2(2). Similar to other
architectures, let's make sure everyone's on the same code path by
having all implementations of renameat() go via renameat2().

I've also moved the existing rename()-in-terms-of-renameat() to be in
terms of renameat2() to cut out the middleman!

Test: treehugger

# 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" | arches
# arches ::= arch | arch "," arches
# arch ::= "arm" | "arm64" | "x86" | "x86_64" | "lp32" | "lp64"
#
# 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, run via
# genrules in Android.bp.
