Debug namespace re-structure

[s1na]

The debug namespace is cluttered with a mix of methods used for low-level client debugging and anything that wasn't standardised into the eth namespace. Creating this issue to track and decide how to go forward with this.

I'll start with a list of all the methods (50 in total):

• eth:

  • Public:
    • DumpBlock (can be potentially modified to make use of snapshots when available)
    • AccountRange
  • Private:
    • Preimage
    • GetBadBlocks
    • StorageRangeAt
    • GetModifiedAccountsByNumber
    • GetModifiedAccountsByHash
    • GetAccessibleState

• les (private):

  • FreezeClient

• internal/ethapi:

  • Public:
    • GetHeaderRlp
    • GetBlockRlp
    • TestSignCliqueBlock
    • PrintBlock
    • SeedHash
  • Private:
    • ChaindbProperty (we can list the possible properties on the website)
    • ChaindbCompact
    • SetHead
    • DbGet

• eth/tracers (private):

  • TraceChain
  • TraceBlockByNumber
  • TraceBlockByHash
  • TraceBlock
  • TraceBlockFromFile
  • TraceBadBlock
  • StandardTraceBlockToFile
  • IntermediateRoots
  • StandardTraceBadBlockToFile
  • TraceTransaction
  • TraceCall

• internal/debug:

  • Verbosity
  • Vmodule
  • BacktraceAt
  • MemStats
  • GcStats
  • CpuProfile
  • StartCPUProfile
  • StopCPUProfile
  • GoTrace
  • StartGoTrace
  • StopGoTrace
  • BlockProfile
  • SetBlockProfileRate
  • WriteBlockProfile
  • MutexProfile
  • SetMutexProfileFraction
  • WriteMutexProfile
  • WriteMemProfile
  • Stacks
  • FreeOSMemory
  • SetGCPercent

  This is the list of methods not documented on the website:

  ['intermediateroots', 'tracebadblock', 'chaindbcompact', 'getheaderrlp', 'accountrange', 'setmutexprofilefraction', 'getmodifiedaccountsbyhash', 'mutexprofile', 'preimage', 'writemutexprofile', 'storagerangeat', 'freezeclient', 'printblock', 'chaindbproperty', 'dbget', 'testsigncliqueblock', 'getmodifiedaccountsbynumber', 'setgcpercent', 'freeosmemory', 'tracechain', 'getbadblocks', 'getaccessiblestate']
  

  Also traceChain is not exposed to JS (Edit: Ah I remember/see now it's because traceChain returns a subscription)
