b312114719 pkt: don't convert endian on header. 
This is now only used for internal tests, so endian conversion is overkill.

e97e8988f8 ccan: import isaac and dependencies. 
We could probably just use Openssl's RAND_pseudo_bytes, but this gives
a nice interface to get a number between 1 and N.

A halfway house between the horror of dynamic generation and the fail of

aeedafc20f Switch to bitcoind by default. 
I haven't implemented getting transactions from alphad (it needs the values
for the inputs, too), so switch to bitcoind.

4b02c6f558 locktime: nice abstractions for absolute and relative locktimes. 
I got confused navigating these, especially since Alpha and Bitcoin

4c42930940 bitcoin/tx, protobuf_convert: support BIP68 as implemented. 
The format for both the nSequence field and the stack arg for
OP_CHECKSEQUENCEVERIFY is either:

  Time-relative:	[Bit 22 = 1] 00000 <time-shifted-by-9>
  Block-relative:	[Bit 22 = 0] 00000 <number of blocks>
