[PATCH 0/2] util: Add thread-safe qemu_strerror() function

[Yohei Kojima]

This patch series adds qemu_strerror() function, which is thread-safe
version of the libc strerror(). The first patch adds the
qemu_strerror() funciton, and the second patch replaces strerror()
function in linux-user/* with qemu_strerror() function.

Because it involves thread-safety, and the strerror_r()
function called by qemu_strerror() has different type signatures between
architectures because of historical reason, the implementation of
qemu_strerror is a bit complicated.

All tests except for skipped ones are passed in my environment (x86_64
linux).
