Denys Vlasenko 82bb78c149 Use single fprintf in verror_msg()

This change partially reverts commit 44d0532.

In code before commit 44d0532, single fprintf was used on purpose:
we want to send entire message as one write() call. Since stderr
is unbuffered, separate fprintf's to it always result in separate
writes, they are not coalesced. If we aren't the only program
which writes to this particular stderr, this may result
in interleaved messages.

Since this function is not performance critical, I guess
it's ok to make it less efficient.

* strace.c (verror_msg): Attempt to print the message in single
write operation. Use separate fprintfs as a fallback if malloc fails.

README

This is strace 4.0, a system call tracer for SunOS 4.x, Linux, System
V release 4, Solaris 2.x and Irix 5.x.  strace is released under a
Berkeley-style license at the request of Paul Kranenburg; see the file
COPYRIGHT for details.

Read the INSTALL file for generic instructions on how to install
strace.  If configure cannot guess your system configuration, you can
specify it on the command line after the other options like this:

	./configure --prefix=/usr i486-linux

A single sunos4.1 binary should work on all the sun4, sun4c and sun4m
kernel architectures.  Let me know if sun4d doesn't work.  Other
i486-*-sysv4 systems may work with little or no tweaking.

See the file NEWS for information on what has changed in recent
versions.

See the file PORTING if you like strace but it doesn't work on an
operating system you use frequently.

See the file CREDITS to see who has contributed to strace.

See the file TODO if you feel like helping out.

You can get the latest version of strace from its homepage at
http://sourceforge.net/projects/strace/ .

Please send bug reports and enhancements to the strace
mailinglist at strace-devel@lists.sourceforge.net, or directly to
Wichert Akkerman <wakkerma@debian.org>
