[ruby-core:81522] [Ruby trunk Bug#13616] Zlib::GzipReader#pos underflows after calling #ungetbyte or #ungetc at start of file

Issue #13616 has been updated by haines (Andrew Haines).
File 0001-Fix-underflow-of-Zlib-GzipReader-pos.patch added
Here's an attempt at a patch to check if pos will be negative and handle that scenario accordingly.
----------------------------------------
Bug #13616: Zlib::GzipReader#pos underflows after calling #ungetbyte or #ungetc at start of file
https://bugs.ruby-lang.org/issues/13616#change-65229
* Author: haines (Andrew Haines)
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
* ruby -v: ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-darwin16]
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
After calling `#ungetbyte` or `#ungetc` at the start of file, `Zlib::GzipReader#pos` should be negative. However, the calculation uses unsigned integers, and underflow occurs.
Instead of the expected -1, the below outputs 18446744073709551615 on my machine:
~~~ ruby
require 'zlib'
gz = Zlib::GzipReader.new(StringIO.new([
31, 139, 8, 0, 44, 220, 209, 71, 0, 3, 51, 52, 50, 54, 49, 77,
76, 74, 78, 73, 5, 0, 157, 5, 0, 36, 10, 0, 0, 0
].pack("C*")))
gz.ungetbyte 0x21
p gz.pos
~~~
`#read` still returns the correct string (`"!12345abcde"` in this case).
