f378d8f9dc Fix _dns_ghbyname() to return NS_TRYAGAIN instead of NS_NOTFOUND 
on temporary nameserver failure. This is necessary to get
getipnodebyname(3) to correctly return h_errno=TRY_AGAIN instead
of HOST_NOT_FOUND.

ebdf5cfddd The previous commit changed the behavior of nsdispatch() in the 
case where an /etc/nsswitch.conf file was present, but could not
be opened (e.g. due to permissions).  Previously, the open failure
condition was suppressed, and the built-in defaults were used.  In
revision 1.11, however, propagated the open failure causing all
nsdispatch() invocations to return NS_UNAVAIL, and thus many APIs
including getpwnam and gethostbyname unconditionally failed.

This commit restores the previous behavior.

aeb757d841 Fix Yet Another 16 byte stack alignment bug. Thankfully, this one is 
solved by a simple 'make world'.  The signalcontext function was going
to the trouble of generating an even 16 byte alignment, but in fact it
needed to be odd aligned to simulate the 8-byte return address having
been pushed by the caller.  This fixes yet another group of crashes in
applications using libpthread.  And yet again, it was my fault all along.

While here, rename the duplicate internal ctx_wrapper() functions to
makectx_wrapper() and sigctx_wrapper() so that traces aren't ambiguous.

7ec3e33301 When a dynamic NSS module is built and linked against a thread 
library, it may pull in that thread library at run time.  If the
process started out single-threaded, this could cause attempts to
release locks that do not exist.  Guard against this possibility by
checking __isthreaded before invoking thread primitives.

A similar problem remains if the process is linked against one thread
library, but the NSS module is linked against another.  This can only
be avoided by careful design of the NSS module.
