d9f3b365a3 configure: ac_cv_ -> curl_cv_ for write-only vars 
These configure vars are modified in a curl-specific way but never
evaluated or loaded from cache, even though they are designated as
_cv_. We could either implement proper AC_CACHE_CHECKs for them, or
remove them completely.

Fixes #603 as ac_cv_func_gethostbyname is no longer clobbered, and
AC_CHECK_FUNC(gethostbyname...) will no longer spuriously succeed after
the first configure run with caching.

`ac_cv_func_strcasecmp` is curious, see #770.

`eval "ac_cv_func_$func=yes"` can still cause problems as it works in
tandem with AC_CHECK_FUNCS and then potentially modifies its result. It
would be best to rewrite this test to use a new CURL_CHECK_FUNCS macro,
which works the same as AC_CHECK_FUNCS but relies on caching the values
of curl_cv_func_* variables, without modifiying ac_cv_func_*.

4b639dbc74 configure: ac_cv_ -> curl_cv_ for r/w vars 
These configure vars are modified in a curl-specific way and modified by
the configure process, but are never loaded from cache, even though they
are designated as _cv_. We should implement proper AC_CACHE_CHECKs for
them eventually.

14c8b45528 configure: ac_cv_ -> curl_cv_ for all cached vars 
This was automated by:

sed -b -i -f <(ack -A1 AC_CACHE_CHECK | \
               ack -o 'ac_cv_.*?\b' | \
               sort -u | xargs -n1 bash -c \
                    'echo "s/$0/curl_cv_${0#ac_cv_}/g"') \
    $(git ls-files)

This only changed the prefix for 16 variables actually checked with
AC_CACHE_CHECK.

now works correctly so this patch enables it there.

358c5c0745 strlcat: remove function 
This function was only used twice, both in places where performance
isn't crucial (socks + if2ip). Removing the use of this function removes
the need to have our private version for systems without it == reduced
amount of code.

Also, in the SOCKS case it is clearly better to fail gracefully rather
than to truncate the results.

This work was triggered by a bug report on the strcal prototype in
strequal.h.

strlcat was added in commit db70cd28 in February 2001!

dddcd3b042 curl-functions.m4: update detection logic of getaddrinfo() thread-safeness 
Take in account that POSIX standard Issue 7 drops h_errno support. Now, we also
consider getaddrinfo() to be thread-safe when (_POSIX_C_SOURCE >= 200809L) or
(_XOPEN_SOURCE >= 700) independently of whether h_errno exists or not.

f1db21218b write extended attributes by using fsetxattr 
Instead of reopening the downloaded file, fsetxattr uses the (already
open) file descriptor to attach extended attributes. This makes the
procedure more robust against errors caused by moved or deleted files.

a7e4022d6b Related with the threadsafe capability of getaddrinfo: 
- Constantine Sapuntzakis reported that Darwin 6.0 a.k.a. MAC OS X 10.2
  and newer have a threadsafe getaddrinfo.

- Fix Dragonfly BSD triplet detection.

- In case the hard-coded knowledge says that getaddrinfo is threadsafe,
  an additional check is done to verify that h_errno is also defined.
  If h_errno isn't defined, we finally assume that it isn't threadsafe.
  Jamie Lokier provided the inspiration for this extra check.
