dispatch: catch KeyboardInterrupt more broadly
Because _runcatch() can run long operations in its exception handler,
it wasn't enough to catch KeyboardInterrupt at the same level. For
example, "hg unknown" will load all extension modules, so we could
easily make it crashed by Ctrl-C.
histedit: have dropmissing abort on empty plan
We noticed that many users have the intuition of laving the editor empty when
they want to abort the operation. The fact that dropmissing allows user to
delete all edited commits is not intuitive even for users that asked for it.
Let's prevent people from this footgun.
streamclone: fix error when store files grow while stream cloning
Effectively a backout of

9fea6b38a8da.
chgserver: handle ParseError during validate
Currently the validate command in chgserver expects config can be loaded
without issues but the config can be broken and chg will print a stacktrace
instead of the parsing error, if a chg server is already running.
This patch adds a handler for ParseError in validate and a new instruction
"exit" to make the client exit without abortmsg. A test is also added to make
sure it will behave as expected.
