Specification
===============
Transactions will have a new field, nBlockExpiry, which will set the block height after which transactions will be removed from the mempool if they have not been mined.
Transactions will have a new field, nExpiryHeight, which will set the block height after which transactions will be removed from the mempool if they have not been mined.
The data type for nBlockExpiry will be uint32_t. If used in combination with nLockTime, both nLockTime and nBlockExpiry must be block heights. nBlockExpiry will never be a UNIX timestamp, unlike nLockTime values.

Default: TBD. Current proposal is 24 blocks, or about 1 hour assuming 2.5 minute block times. Can add a config option to set user's default.
Minimum: No minimum
Maximum: 500000000, about 380 years
No limit: To set no limit on transactions (so that they do not expire), nBlockExpiry should be set to UINT_MAX.

Every time a transaction expires and should be removed from the mempool, so should all its dependent transactions.
