libpcp, pcp-xsos: finer grained string output control in pmPrintValue
Implement a mechanism in pmPrintValue for producing single-line value
output, giving shell scripts a chance to operate sensibly with whacky

Resolves Red Hat bugs RHEL-67164 and RHEL-67148.

+.BR PCP_SQUASH_NEWLINES .
+When set in the environment of the calling process, and the
