Reject transactions with excessive numbers of sigops
Remove tx from AlreadyAskedFor list once we receive it, not when we process it.
Simplify and rename CheckWork to ProcessBlockFound
Allow -onlynet=onion to be used

Just an alias for onlynet=tor, but matches the new name
of the proxy option -onion= better.
Add IsReachable(net) function

Allows other parts of the program to query for reachable
status of a network. Similar to IsLimited(net).
Add GetNetworkName function

Returns the network name for an Network enum.
Fixes ignored qt 4.8 codecs path on windows when configuring with --with-qt-libdir
[Qt] move SubstituteFonts() above ToolTipToRichTextFilter

- doesn't belong to the ToolTipToRichTextFilter class so move it up
[Qt] ensure all class attributes are init to 0

- in BitcoinGUI and UnitDisplayStatusBarControl
[Qt] use BitcoinGUI::DEFAULT_WALLET constant in bitcoin.cpp
[Qt] disable tray interactions when client model set to 0

- this prevents the ability to fiddle around with the system tray when
  already shutting down (e.g. on slow shutdowns because of a proxy delay)
- extends solution for #4360
URLs containing a / after the address no longer cause parsing errors.
depends: add shared dependency builder

See the README's in depends for documentation
build: fix FDELT_TYPE configure check

This probably never worked properly. Confirmed working now with every compiler
I throw at it.
libc-compat: add new symbol that's now needed
Add a way to limit deserialized string lengths

and use it for most strings being serialized.
Simplify serialize.h's exception handling

Remove the 'state' and 'exceptmask' from serialize.h's stream implementations,
as well as related methods.

As exceptmask always included 'failbit', and setstate was always called with
bits = failbit, all it did was immediately raise an exception. Get rid of
those variables, and replace the setstate with direct exception throwing
(which also removes some dead code).

As a result, good() is never reached after a failure (there are only 2
calls, one of which is in tests), and can just be replaced by !eof().

fail(), clear(n) and exceptions() are just never called. Delete them.
