This PR makes use of go 1.13 error handling, wrapping errors and using
errors.Is to check a wrapped root-cause. It also removes the travis
builders for go 1.11 and go 1.12.

core, light: rewrite setHead function
core, eth: fix downloader unit tests
core: add receipt chain insertion test
core: use constant instead of hardcoding table name
core: fix rollback
core: fix setHead
core/rawdb: remove canonical block first and then iterate side chain
core/rawdb, ethdb: add hasAncient interface
eth/downloader: calculate ancient limit via cht first
core, eth, ethdb: lots of fixes
* eth/downloader: print ancient disable log only for fast sync
* core, eth, trie: bloom filter for trie node dedup during fast sync
* eth/downloader, trie: address review comments
* core, ethdb, trie: restart fast-sync bloom construction now and again
* eth/downloader: initialize fast sync bloom on startup
* eth: reenable eth/62 until we properly remove it
* cmd, eth: Added in the flag to step geth once sync based on input
* cmd, eth: 16400 Add an option to stop geth once in sync.
* cmd: 16400 Add an option to stop geth once in sync. WIP
* cmd/geth/main, les/fletcher: added in light mode support
* cmd/geth/main, les/fletcher: Cleaned Comments and code for light mode
* cmd: 16400 Fixed formatting issue and cleaned code
* cmd, eth, les: 16400 Fixed formatting issues
* cmd, eth, les: Performed gofmt to update formatting
* cmd, eth, les: Fixed bugs resulting formatting
* cmd/geth, eth/, les: switched to downloader event
* eth: Fixed styling and gen_config
* eth/: Fix nil error in config file
* cmd/geth: Updated countdown log
* les/fetcher.go: Removed depcreated channel
* eth/downloader.go: Removed deprecated select
* cmd/geth, cmd/utils: Fixed minor issues
* eth: Reverted config files to proper format
* eth: Fixed typo in config file
* cmd/geth, eth/down: Updated code to use header time stamp
* eth/downloader: Changed the time threshold to 10 minutes
* cmd/geth, eth/downloader: Updated downloading event to pass latest header
* cmd/geth: Updated main to use right timer object
* cmd/geth: Removed unused failed event
* cmd/geth: added in correct time field with type assertion
* cmd/geth, cmd/utils: Updated flag to use boolean
* cmd/geth, cmd/utils, eth/downloader: Cleaned up code based on recommendations
* cmd/geth: Removed unneeded import
* cmd/geth, eth/downloader: fixed event field and suggested changes
* cmd/geth, cmd/utils: Updated flag and linting issue
* ethdb: add Putter interface and Has method
* ethdb: improve docs and add IdealBatchSize
* ethdb: remove memory batch lock
Batches are not safe for concurrent use.
* core: use ethdb.Putter for Write* functions
This covers the easy cases.
* core/state: simplify StateSync
* trie: optimize local node check
* ethdb: add ValueSize to Batch
* core: optimize HasHeader check
This avoids one random database read get the block number. For many uses
of HasHeader, the expectation is that it's actually there. Using Has
avoids a load + decode of the value.
* core: write fast sync block data in batches
Collect writes into batches up to the ideal size instead of issuing many
small, concurrent writes.
* eth/downloader: commit larger state batches
Collect nodes into a batch up to the ideal size instead of committing
whenever a node is received.
* core: optimize HasBlock check
This avoids a random database read to get the number.
* core: use numberCache in HasHeader
numberCache has higher capacity, increasing the odds of finding the
header without a database lookup.
* core: write imported block data using a batch
Restore batch writes of state and add blocks, tx entries, receipts to
the same batch. The change also simplifies the miner.
This commit also removes posting of logs when a forked block is imported.
* core: fix DB write error handling
* ethdb: use RLock for Has
* core: fix HasBlock comment
