Add public methods for accessing the pertinent information about a ReaderException

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Pass any non-printable character (any in 
"[^\t\n\r\u0020-\u007E\u0085\u00A0-\uD7FF\uE000-\uFFFC]") to StreamReader
2.
3.

What is the expected output? What do you see instead?
N/A

What version of SnakeYAML are you using? On what Java version?
1.10-SNAPSHOT

Please provide any additional information below. (Often a failing test is
the best way to describe the problem.)
JRuby uses SnakeYAML as its YAML parser and emitter. When the parser fails, 
JRuby is thrown a ReaderException, but it might be desirable to wrap it and 
present a different error message to the user.

Currently, the only way to do this is to parse ReaderException.toString() and 
extract the information. This is obviously brittle.

ReaderException.getChar(), ReaderException.getName(), 
ReaderException.getPosition() will be welcome additions.

I meant that the non-printable characters are any in 
"[\t\n\r\u0020-\u007E\u0085\u00A0-\uD7FF\uE000-\uFFFC]", which is the complete 
opposite of what I showed above. Sorry about that.

No problem. I think ReaderException.getName() is useless, but it will be added 
anyway for completeness.
