0b92a3c933 Introduce hardened xsprintf/xsnprintf macros
Let's try to future/fool-proof code a bit by introducing variants

They are deemed to be the default choice for printing to some local
string buffer where no sensible error handling is implemented.

* xstring.h: New file.
* Makefile.am (strace_SOURCES): Add it.

7d56c3d808 Makefile.am: build top directory first
This solves potential issues when tests run first and strace is rebuilt
only after they have finished.  As noted in [1], providing the current
directory explicitly should help.

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.
