Currently, the error() is always printing the output to the console
through 'stdout'. This does not follow redirection which is good when
you want to know error while redirecting commands output to a file.
However, there are situations that you want to hide error messages or
redirect it into somewhere else.
Using 'set stderr' command, it can be changed to three different
destination - fixed 'stdout', following redirection (fp), or a custom
file path.
crash> set stderr
stderr: stdout
crash> sym 0x523 > /dev/null
sym: invalid address: 0x523
crash> set stderr fp
stderr: fp
crash> sym 0x523 > /dev/null
crash> set stderr /tmp/err.log
stderr: /tmp/err.log
crash> sym 0x523 > /dev/null
crash> set stderr stdout
stderr: stdout
crash> sym 0x523 > /dev/null
sym: invalid address: 0x523
When using file path for 'set stderr', we only accept the length smaller than PATH_MAX (4096).
