…sactions

max number of path
max number of operations inside a transaction
max number of signers tied to an account
max number of signatures on a transaction

This one also fixes an actual bug in Peer.cpp

* split transaction from transaction result into two different files
* use transaction sets as the unit used to save transactions

CreateOffer transaction with a `offerId` and `amount` set to zero.

old code was not allowing sending credits as XLM via offers

previous behavior was to return "success" with no offers taken and no offer created - which could be misleading

having not enough offers around is not related to sendmax

This should make differenciating errors from success codes simpler when looking at history.

This was blocked by proper support of enums in XDRC

this allows to
* make it clearer for integrators that a transaction is submitted
(without having a result as there is no result yet)
* remove txDUPLICATE from the protocol
* only expose the result if there was a validation error

…data

added dedicated XDR types for meta data (was using bucket list ones)

previously was only enforcing receiving but not sending

added CreatePassiveOffer

don't allow unknown flags

…d of the transaction.

This makes the primary tracking of account balances simpler

keeps only one message per node
new message types

places to version the protocol

…xplicit regardless of the reason

old code was only doing this for the destination account

was int32

first bytes are now union data

generic Signature type replaced it

prefix data being signed by some context data

documentation update

convention is that they are negative

- src/ now contains only stellar software.
- lib/ now contains all third-party software.
- src/ has its own Makefile (so xdrc can be built first).
- stellar-core now ends up in src/stellar-core.
- Only stellar-core binary is installed (not libsodium, xdrpp)
- Massive reduction of Makefile.am sizes
    - Source file lists auto-generated by ./make-mks script.
    - Most third-party stuff crammed into lib/lib3rdparty.a
    - No need for libtool since all libraries static
    - All files now compiled with the same CPPFLAGS
    - .x files generate .h files in same directory
- autogen.sh reinitializes all submodules unless given -s flag
- Non-standard compile options (color, etc.) are disabled by default.
    - Use ./configure --enable-sdfprefs to re-enable them.
    - Warning-related flags now set and overridable with WFLAGS
- .dir-locals.el fixed to make it possible to put tabs in Makefiles
- Always rebuild StellarCoreVersion.h to guarantee it is correct
    - Preserve timestamp to avoid unnecessary recompilation

allow 12 character long asset codes fixes #616
name offers in a more intuitive way fixes #573

this avoids the possibility of invalidating mSourceAccount

This commit only sets it 0

as it's now a struct we need one in case we want to add new fields shared between types
