Clarify "relationship to POSIX" section

[Jeff Johnson]

Current snapshots contain information about LSB 5.0 that is just forwarded from
LSB 4.1 except that the base standard link has automatically updated to POSIX
2008.

Copied in full here; the question is, should we make adjustments? The report
referenced is no longer entirely appropriate, since it compares an old LSB to
an old POSIX. Indeed the paragraph that states it's a comparison to POSIX 2001
is wrong, but this was picked up by simply changing codes. The reference to
the Specification Authority references a group that hasn't formally existed for
many many years now, but could be reconsitituted if necessary, so not sure what
to do with that.

Chapter 6. Relationship To ISO/IEC 9945 POSIX

This specification includes many interfaces described in POSIX 1003.1-2008
(ISO/IEC 9945-2009). Unless otherwise specified, such interfaces should behave
exactly as described in that specification. Any conflict between the
requirements described here and the POSIX 1003.1-2008 (ISO/IEC 9945-2009)
standard is unintentional, except as explicitly noted otherwise.

    Note: In addition to the differences noted inline in this specification,
PDTR 24715 has extracted the differences between this specification and POSIX
1003.1-2008 (ISO/IEC 9945-2009) into a single place. It is the long term plan
of the Linux Foundation to converge the LSB Core Specification with ISO/IEC
9945 POSIX.

The LSB Specification Authority is responsible for deciding the meaning of
conformance to normative referenced standards in the LSB context. Problem
Reports regarding underlying or referenced standards in any other context will
be referred to the relevant maintenance body for that standard.
