Fix httpd config option 'erl_script_nocache'

This fixes the usage of the httpd configuration option
'erl_script_nocache', which got ignored before.

Attention: Before, the option 'script_nocache' also changed the
behavior for mod_esi, now it only affects mod_cgi.
Add Fd usage in rb logging

rb was only accepting physical filenames as log file.
This patch allow rb to accept now any io_device, valid registered name,
except standard_error which is replaced by standard_io.
Creation of two new exported functions : rb:log_list/0-1
that print in log file if existing, otherwise on standard_io.
Add new functions documentation and tests in rb_SUITE.
Forbid returning a match context in beam_validator

If a match context is returned from a function without being converted
back to a plain old binary, the whole VM will crash.
Added primary bootstrap
kernel: sasl: fixed rb.xml docs
make edlin understand a few important control keys

Hi Fredrik,

Please find an updated version of the patch attached to this e-mail. I
hope that you still accept it via e-mail because the former patch was
sent the same way ;-).

I have extended the documentation to list the new key combinations and
added tests to make sure they work.

Kind regards,

Subject: [PATCH] [EDLIN] support a few more control keys

Add support for the following control keys that many users have become
accustomed to:
 - <CTRL>+W         : backward kill word
 - <CTRL>+U         : backward kill line
 - <HOME>           : goto start of line
 - <END>            : goto end of line
 - <CTRL>+<LEFT>    : backward word
 - <CTRL>+<RIGHT>   : forward word

It seems that the <CTRL>+<LEFT|RIGHT> control key sequences are
different between terminal emulators, therefore a few possible
combinations were added (similar to how libreadline is configured).

Documentation and tests are extended to reflect the new functionality.
