e22d025dc8 Simplify block marker metadata (#985)
* wip BlockMarker struct, get rid of PMMRMetadata
* use rewind to init the txhashet correctly on startup, we do not need to track pos via metadata (we have block markers), we do not need to open the txhashset with specific pos (we have rewind)
* better logging on init
* keep rewinding and validating on init, to find a good block
* use validate_roots on chain init

c96838d54d Improve bounding block timestamp (#793)
Fixes #783.
* 2^60 still fails on OSX, experimentally found safe max 2^55
* Handle negative values

I tried to use .abs(), unfortuantely fuzz test kills it with
`panicked at 'attempt to negate with overflow', /Users/travis/build/rust-lang/rust/src/libcore/num/mod.rs:1146:17`

Fuzz test demonstrated that the current implemenation panics on reading from the network when serialized tx. Contains for example huge number of input or outputs. It allows a mailicious sender
to kill the server.

we were not traversing all the way up to the peak if we pruned an entire tree
so rm_log and prune list were inconsistent

otherwise we cannot spend them...
