The fallback function (gf_vsnprintf) to provide a vsnprintf function
if the system library doesn't have one would not compile due to the
variable name for the string's destination buffer not being updated
after the refactor in 2018 in edaaef601d.
This updates the internal logic of gf_vsnprintf to now use the str
variable defined in the function signature.

* libgfortran.h: Remove gfc_xtoa(), adjust gfc_itoa() and
GFC_ITOA_BUF_SIZE.
* io/write.c (write_decimal): conversion parameter is always
gfc_itoa(), so remove it. Protect from overflow.

(write_z): Adjust to new function names.
(write_i, write_integer): Remove last arg of write_decimal.
* runtime/backtrace.c (error_callback): Comment on the use of
gfc_itoa().
* runtime/error.c (gfc_xtoa): Move to io/write.c.
* runtime/string.c (gfc_itoa): Take an unsigned argument,
remove the handling of negative values.
While we have `configure' checks for the individual POSIX 2008 extended
locale functions we refer to and use to guard the respective call sites,
we only verify the presence of `newlocale' for our global feature enable
check. Consequently compilation fails for targets like NetBSD that only
have partial support for POSIX 2008 locale features and in particular
lack the `uselocale' function:

With multiple threads, using an unprotected static variable to check
whether recursion has occured isn't valid, as one thread might have
modified the variable, thus causing another thread to incorrectly
conclude that recursion has occured. This patch avoids this problem
by using a thread-specific variable for the recursion check.

When producing error and warning messages, libgfortran writes a
message by using many system calls. By using vectored writes (the
POSIX writev function) when available and feasible to use without
major surgery, we reduce the chance that output gets intermingled with
other output to stderr.
In practice, this is done by introducing a new function estr_writev in
addition to the existing estr_write. In order to use this, the old
st_vprintf is removed, replaced by direct calls of vsnprintf, allowing
more message batching.
