The new nameref assignment functionality introduced in bash-4.3 did not perform
enough validation on the variable value and would create variables with
invalid names.

Bug-Description:
When bash is running in Posix mode, it allows signals -- including SIGCHLD --
to interrupt the `wait' builtin, as Posix requires. However, the interrupt
causes bash to not run a SIGCHLD trap for all exited children. This patch
fixes the issue and restores the documented behavior in Posix mode.

Bug-Description:
Bash does not clean up the terminal state in all cases where bash or
readline modifies it and bash is subsequently terminated by a fatal signal.
This happens when the `read' builtin modifies the terminal settings, both
when readline is active and when it is not. It occurs most often when a script
installs a trap that exits on a signal without re-sending the signal to itself.
