it's -> its

pet peeve, and I like to imagine I'm not alone.

core/vm: improve jumpdest analysis

core: split same-td blocks on block height

core/vm: fix typos in jump_table.go

Dockerfile: support alltools image beside plain Geth

vendor: add github.com/stretchr/testify test dependency

dockerignore, internal/build: forward correct git folder

* cmd/puppeth: handle encrypted ssh keys

* cmd/puppeth: fix unconvert linter error

* .dockerignore, internal/build: Read git information directly from file

This commit changes the way of retrieving git commit and branch for build
environment from running git command to reading git files directly.

This commit also adds required git files into Docker build context.

fixes: #15346

* .dockerignore: workaround for including some files in .git

github.com/stretchr/testify is a useful library for doing
assertion in tests. It makes assertions in test more less verbose and
more comfortable to read and use.

* build: enable unconvert linter

 - fixes #15453
 - update code base for failing cases

* cmd/puppeth: replace syscall.Stdin with os.Stdin.Fd() for unconvert linter

Fixes #15373

This changes behaviour: before if the owner/amount didn't match, it
resulted in a successful execution without doing anything; now it
results in a failed execution using the revert opcode (remainder gas
is not consumed).

build: enable gofmt and misspell linters

travis: bump Android NDK version and Android Go builder

* build: [finishes #15372] implements generalized linter and travis job

* .travis, build: minor polishes, disable deadcode

All logs in the FilterLog return value would be the same object 
because the for loop captured the pointer to the iteration variable.

* core: allow price bump at threshold

* core: test changes to allow price bump at threshold

* core: reinstate tx replacement test underneath threshold
