cmd/gomobile: sanitize android app package names

https://docs.oracle.com/javase/tutorial/java/package/namingpkgs.html

"This can occur if the domain name contains a hyphen or other special
character, if the package name begins with a digit or other character
that is illegal to use as the beginning of a Java name, or if the
package name contains a reserved Java keyword, such as "int". In this
event, the suggested convention is to add an underscore."

The sanitized name is used for the app package name and the default apk
file name.

Update golang/go#12273

Go support for Mobile devices

The Go mobile repository holds packages and build tools for using Go on mobile platforms.

Package documentation as a starting point:

Caution image

The Go Mobile project is experimental. Use this at your own risk. While we are working hard to improve it, neither Google nor the Go team can provide end-user support.

This is early work and installing the build system requires Go 1.5. Follow the instructions on golang.org/wiki/Mobile to install the gomobile command, build the basic and the bind example apps.


Contributions to Go are appreciated. See https://golang.org/doc/contribute.html.
