da5bf709e6 Consider count_in in Noux terminal-read function
It does not suffice to constrain the amount of returned data with chunk
size of the transport buffer because the client may have specified an
even smaller value. For example, libreadline reads single characters
from the terminal and expects a single character in return. A different
amount is interpreted as EOF.

cc85dc8afb Let GDB monitor use HLT for breakpoints, fix
The patch fixes a corner-case problem with using the two-byte 'INT 0'
instruction for breakpoints. The fix changes the breakpoint instruction
to the single-byte 'HLT'. 'HLT' is a privileged instruction and triggers
an exception when executed in user mode. Patch by Christian Prochaska.

441d672440 Improved interactive GDB monitor run script
The new 'gdb_monitor_interactive.run' script extends the original
'gdb_monitor.run' script with a startup sequence that automates the
initial break-in at the main function of a dynamically linked binary.
Patch by Christian Prochaska.

8c3f832f09 Noux: quote env values, fix
When reading the values of environment variables supplied via Genode
config mechanism, the XML attribute values were taken as is. On the libc
side, however, the values are processed using Genode's 'Arg_string'
functions. When unquoted, 'Arg_string' expects values to be either
identifiers or numbers. In the general case, however, env values cannot
be expected to satisfy these requirements. Hence, it is better to always
quote these values when reading the XML config. An alternative (maybe
better) solution would be to not use the 'Arg_string' classes in the
libc side.

3c54d39307 Provide a default implementation of chdir, fix
The default implementation relies on the sequence open, fchdir, close.
Enable this implementation for the Noux libc plugin.

b5d7a75a22 Return ECHO flag from TIOCGETA ioctl
This patch sets the ECHO flag for the TIOCGETA ioctrl operation. This
flag is examined by libreadline to control the policy of echoing user
input. This patch in needed to run bash in interactive mode in Noux.
