bind: make the default name prefix empty on ObjC Since generated names now have their package names prefixed, the extra prefix, "Go", is both confusing and counter-productive to making the generated ObjC code look like any other native code. Change the default to the empty prefix, while preserving support for an explicit prefix if needed. This is a backwards incompatible change; to keep the old behaviour, specify "-prefix Go" to the gobind or gomobile command. While we're here, fix the Ivy example for the recent change in error returns.

bind: remove error wrappers to preserve error instance identity CL 24800 changed the error representation from strings to objects. However, since native errors types are not immediately compatible across languages, wrapper types were introduced to bridge the gap. This CL remove those wrappers and instead special case the error proxy types to conform to their language error protocol. Specifically: - The ObjC proxy for Go errors now extends NSError and calls initWithDomain to store the error message. - The Go proxy for ObjC NSError return the localizedDescription property for calls to Error. - The Java proxy for Go errors ow extends Exception and overrides getMessage() to return the error message. - The Go proxy for Java Exceptions returns getMessage whenever Error is called. The end result is that error values behave more like normal objects across the language boundary. In particular, instance identity is now preserved: an error passed across the boundary and back will result in the same instance. There are two semantic changes that followed this change: - The domain for wrapped Go errors is now always "go". The domain wasn't useful before this CL: the domains were set to the package name of function or method where the error happened to cross the language boundary. - If a Go method that returns an error is implemented in ObjC, the implementation must now both return NO _and_ set the error result for the calling Go code to receive a non-nil error. Before this CL, because errors were always wrapped, a nil ObjC could be represented with a non-nil wrapper.

bind: param name replacement for invalid unicode names The are three generators that currently call this method: A -> B (1) go -> java (2) go -> objective-c (3) go -> go As discussed below, we only substitute for invalid unicode characters in case (1). **Case 1** Go: From golang.org/ref/spec: Identifiers name program entities such as variables and types. An identifier is a sequence of one or more letters and digits(unicode_digit). The first character in an identifier must be a letter(unicode_letter | "_" ). Java: From https://docs.oracle.com/javase/specs/jls/se7/html/jls-3.html#jls-3.8 `The "Java letters" include uppercase and lowercase ASCII Latin letters A-Z (\u0041-\u005a), and a-z (\u0061-\u007a), and, for historical reasons, the ASCII underscore (_, or \u005f) and dollar sign ($, or \u0024). The $ character should be used only in mechanically generated source code or, rarely, to access pre-existing names on legacy systems.` Therefore, Go's identifiers are checked in case they break these Java rules. **Case 2** There is no objective-c standard specification for valid identifiers. From some testing it seems that Go and objective-c have identical valid identifier rules. **Case 3** Requires no checking.
