Irina Tirdea 1ad10a566e Add getsid system call to bionic 
Add getsid() system call to bionic for
all architectures. This is needed for various tools
(e.g. perf).

Adding the getsid system call was done in 3 steps:
() add getsid system call (function name and syscall
number) to libc/SYSCALLS.TXT
() generate all necessary headers by calling
libc/tools/gensyscalls.py. This patch is adding
the generated files since the build system
does not call gensyscalls.py.
() add the system call signature to libc/include/unistd.h

# this file is used to list all the syscalls that will be supported by
# the Bionic C library. It is used to automatically generate the syscall
# stubs, the list of syscall constants (__NR_xxxx) and the content of <linux/_unistd.h>
#
# each non comment line has the following format:
#
# return_type func_name[:syscall_name[:call_id]]([parameter_list]) (syscall_number|"stub")
#
# note that:
# - syscall_name correspond 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)
# 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 on 32 bits, there is no plan to support
# 64-bit architectures at the moment
#
# - it there is "stub" instead of a syscall number, the tool will not generate any
# assembler template for the syscall; it's up to the bionic implementation to provide
# a relevant C stub
#
# - additionally, if the syscall number is different amoung ARM, and x86, MIPS use:
# return_type funcname[:syscall_name](parameters) arm_number,x86_number, mips_number
#
# the file is processed by a python script named gensyscalls.py
#
