* Renaming androgynous sub-object names according to where they belong
why:
These objects are not explicitly dealt with. They give meaning to
some generic wrapper objects. Naming them after their origin may
help troubleshooting.
* Redefine proof nodes list data type for `snap/1` wire protocol
why:
The current specification suffered from the fact that the basic data
type for a proof node is an RLP encoded hexary node. This slightly
confused the encoding/decoding magic.
details:
This is the second attempt, now wrapping the `seq[Blob]` into a
wrapper object of `seq[SnapProof]` for a distinct alias sequence.
In the previous attempt, `SnapProof` was a wrapper object holding the
`Blob` with magic applied to the `seq[]`. This needed the `append`
mixin to strip the outer wrapper that was applied to the `Blob` already
when it was passed as argument.
* Fix some prototype inconsistency
why:
For easy reading, `getAccountRange()` handler return code should
resemble the `accoundRange()` anruments prototype.
* Enable `snap/1` accounts range service
* Allow to change the garbage collector to `boehm` as a Makefile option.
why:
There is still an unsolved memory corruption problem that might be
related to the standard `gc`. It seemingly goes away if the `gc` is
changed to `boehm`.
Specifying another `gc` on the make level simplifies debugging and
development.
* Code cosmetics
details:
* updated exception annotations
* extracted `worker_desc.nim` from `full/worker.nim`
* etc.
* Implement option to state a sync modifier file
why:
This allows to specify extra sync type specific options which might
change over time. This file is regularly checked for updates.
* Implement a threshold when to suspend full syncing
why:
For a test scenario, a full sync beep may work as a local snap server.
There is no need to download the full block chain.
details:
The file containing the pivot specs is specified by the
`--sync-ctrl-file` option. It is regularly parsed for updates.
