92e347b556 Add copyright headers to some files that lack them 
We do our best to keep copyright headers up to date, yet
git history provides better information on this subject
and is more accurate than copyright headers.

51d89ef0a0 Refactor get_syscall_args() and get_error() 
* linux/*/get_error.c: Rename all arch-specific implementations
of get_error() to arch_get_error().
* linux/*/get_syscall_args.c: Rename all arch-specific implementations
of get_syscall_args() to arch_get_syscall_args().
* syscall.c (get_syscall_args, get_error): New functions.
(tamper_with_syscall_exiting, get_syscall_result): Do not clear
tcp->u_error before get_error() invocation as the latter does it now.

917c2ccf3a Refactor stack pointers 
Change all linux/*/arch_regs.c to provide either ARCH_SP_REG
or ARCH_SP_PEEK_ADDR.  Introduce get_stack_pointer(), rewrite
all code accessing stack pointers to use get_stack_pointer().

clean up this confusion.

72aba2be32 Move is_negated_errno() to new header negated_errno.h 
Move is_negated_errno() to a separate new header file negated_errno.h
and include it just for architectures which require it.

is_negated_errno() is not used on those architectures
that have a dedicated register to signal a syscall error.

The issue was raised when compiling with clang, which is more
strict regarding semantics of unused static inline functions
defined in C files and will issue a -Wunused-function warrning
if they are not used anywhere.

* syscall.c (is_negated_errno): Move to ...

5105d4ac96 Cleanup print_pc 
Apparently, there are only two types of instruction pointer printers
depending on the architecture: those that print a register that was
fetched earlier, and those that fetch a register themselves using upeek.
With this change, architectures of the first type have ARCH_PC_REG
defined in their arch_regs.c file, architectures of the first type
have ARCH_PC_PEEK_ADDR defined there, and the common code in syscall.c
uses these macros to print the instruction pointer.
