Marius Strobl 29b6820f87 Merge r202882 from amd64/i386: 
For PT_TO_SCE stop that stops the ptraced process upon syscall entry,
syscall arguments are collected before ptracestop() is called. As a
consequence, debugger cannot modify syscall or its arguments.

In syscall(), reread syscall number and arguments after ptracestop(),
if debugger modified anything in the process environment. Since procfs
stopevent requires number of syscall arguments in p_xstat, this cannot
be solved by moving stop/trace point before argument fetching.

Move the code to read arguments into separate function
fetch_syscall_args() to avoid code duplication. Note that ktrace point
for modified syscall is intentionally recorded twice, once with original
arguments, and second time with the arguments set by debugger.

PT_TO_SCX stop is executed after cpu_syscall_set_retval() already.
