libfetch: fix pkg_install core dumps reported in PR 57179

Sync with pkgsrc and try to fix more memory corruption from PR/57179.

Rebase to HEAD as of a few days ago.

sync with head.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

Annotate format strings. Add a bunch of int casts for size limits.

avoid a strict aliasing problem copying the mapped v4 address out of
a ipv6 address.

fix gcc array out of bounds confusion.

delint

add missing paren

It is a lot nicer to getenv() what you need once and makes the code a lot
more readable.

PR 43013 by Brook Milligan: fetch(3) violates RFC 1738 for ftp:// URLs
if the home directory is not the root directory.

Remember the current directory the first time a CWD / CDUP has to be
issued. Use the document as full URL if the URL started with two /
(quoted or not), otherwise append it to the initial directory.
