* WIP: Implement HTTPS interception detection by Durumeric, et. al.
Special thanks to @FiloSottile for guidance with the custom listener.
* Add {{.IsMITM}} context action and {mitm} placeholder
* Improve MITM detection heuristics for Firefox and Edge
* Add tests for MITM detection heuristics
* Improve Safari heuristics for interception detection
* Read ClientHello during first Read() instead of during Accept()
As far as I can tell, reading the ClientHello during Accept() prevents
new connections from being accepted during the read. Since Read() should
be called in its own goroutine, this keeps Accept() non-blocking.
* Clean up MITM detection handler; make possible to close connection
* Use standard lib cipher suite values when possible
* Improve Edge heuristics and test cases
* Refactor MITM checking logic; add some debug statements for now
* Fix bug in MITM heuristic tests and actual heuristic code
* Fix gofmt
* Remove debug statements; preparing for merge
* Add Files action to template context. (#1198)
* Fixes to testFiles().
- Set os.ModePerm on directories created during test.
- Use filepath.Join() to create directory path.
- Use Fatalf, not Fatal.
* Make additional fixes to test cases.
* Fix test cases to use correct path format.
Dir.Open() in net/http requires '/'-separated paths while
filepath.Join() may produce paths with different separator.
* Remove directory created by test at end of loop.
* Close the FileSystem before returning.
* Initialize names slice to the number of entries.
Also, do not call os.RemoveAll() unless the path to the directory
is a valid one.
* * Added support for environment variables to 'templates' module.
* Fixed flaw in test caused by environment variable ordering during testing on CI.
* Updated some local variables to camel-case.
* Reverted changes to replacer as environment variables are processed elsewhere.
* Removed PrintEnv functionality in favour of documenting using template range.
