remove AMENDED-notes (the last functional spec change to match with the
implementation is from 2014, other amendments are clarifications)

Have this match simple-prefix-code and redirect to "Normal Code Length
Code" as the added indirection to 'code-length-code' and the undefined
'encoded-code-lengths' doesn't add much.

- add missing '(' in DIV_ROUND_UP
- in 6.2.2, rename 'pos' variable reference to match definition
('position')

this makes the output from img2webp and the ordering in doc/tools.md and
man/img2webp.1 consistent

Both are global settings. Modifying them at the frame level is left as a
follow up based on need.

'zero alpha pixels' was a bit hard to parse; replace this with something
more explicit

this is similar to an earlier change for most of the code examples:
7a0a9935 doc/*.txt: restrict code to 69 columns
some renderers may limit output to 72 and use a 3 space indent; this
avoids overflowing into the margin
Bug: webp:448
Change-Id: I2e8d66f598889c7bd824e911ea01fd70f98a4130
The distance code read from the bitstream is reduced by 1 before doing
the lookup. The prose describing the lookup was correct, the pseudocode
failed to subtract 1 and used x/y instead of xi/yi from the lookup.

clarify that the data is after the size specified by the file size in
the header; an alternate way to read the previous statement was that the
data was after the 'WEBP' fourcc.
