POSIX message queues:  Move mq_setattr() and mq_getattr() from nuttx/libc/mqueue to nuttx/sched/mqueue.  Also add sysyscall support for mq_setattr() and mq_getattr().  This is necessary in protected and kernel builds because in those cases the message queue structure is protect and cannot be accessed directly from user mode code.  Noted by Jouko Holopainen.

Networking:  Modify how callback structures are stored to avoid another potential use of a stal pointer.

mq_timedreceive() move the location where the errno value is set; the TIMEDOUT errno setting was being overwritten by subsequent actions before returning.  Noted by Freddie Chopin.

Extend the mkconfig tool so that it can dequote a quoated list of quoated strings.  THTTPD uses such a configration setting to provide the list of index files.

Damn.  THTTPD will not yet run with binfs because it wants an index.html file.  THTTPD does support indexing directories if CONFIG_THTTPD_GENERATE_INDICES=y, but there are some compilation issues that need to be fixed when that option is selected.

Olimex LPC1766STK.  Add an example configuration showing how to build apps/netutils/thttpd using binfs

Add support uClibc++ excpetions.  This involves additional handling for relative relation types, additional support for unwinding, as well as additional changes.  The culmination of a big effort fromo Leo Aloe3132

LPC17xx: All configurations that had the LPC17xx ethernet driver enabled have CONFIG_NET_NOTINTS=y enabled and also the HP worked which is now needed in those configurations

tools/configure.c: Fix test for the extence of the apps/ dir.  This is part of SourceForge Ticket #39

tools/configure.c: Fix backward interpretation of options, -l was selecting Windows and -w was selecting Linux. This is part of SourceForege Ticket #39

TCP connect.  Move the location where the socket is marked as connected in order to avoid a potential race condition
