f6a82a7c98 When messages were no longer available in an upstream stream a mirror could wedge and not resolve. 
This fixes that scenario by detecting the situation and inserting skip msgs to catch up.

d929ee1348 Check errors when removing test directories and files 
Currently in tests, we have calls to os.Remove and os.RemoveAll where we
don't check the returned error. This hides useful error messages when
tests fail to run, such as "too many open files".

This change checks for more filesystem related errors and calls t.Fatal
if there is an error.

e44275b963 Consolidate temporary test files and directories 
Currently, temporary test files and directories are written in lots of
different paths within the OS's temp dir. This makes it hard to know
which files are from nats-server and which are unrelated. This in turn
makes it hard to clean up nats-server test files.

a75e8f8c80 Fix for an issue with multiple restarts that showed stalled and sometimes lost streams. 
The issue was when a state was removed from a server and restarted it would catch up properly.
However upon cluster restart the system could exhibit strange behaviors. This was due to on
catchup not properly creating a meta snapshot when one was received, leaving no meta state to recover.

b316cccfd1 Fixed a quorum formation issue that caused truncation 
When a new leader is elected it has to give everyone a chance to reply,
so that we can observe rejections with higher term.

The maximum election timeout is 7.5 seconds.
The new behavior of waiting for the election timeout caused unit tests
to fail. Hence upping the timeout there as well.

299f44cddf This changes our behaviors for streams and peer removals in several ways. 
First we no longer try to auto-remap stream assignments on peer removals from the system.
We also now can always respond to stream info requests if at least a member is running.
