5b3be2ee35 getaddrinfo is fully thread safe on solaris versions which 
implement the function even when h_errno is not a macro.

The h_errno macro test now only done on systems for which there
is no hard coded knowledge about getaddrinfo's thread safeness.

5e75817d44 Assume that getaddrinfo is thread safe, unless hard coded 
knowledge says the contrary or h_errno is not defined.

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.

Add some comments to better understand what the regex's pretend to achieve.

ce6731baf1 Symbol hiding configure options renamed to the hopefully less ambiguous 
--enable-symbol-hiding and --disable-symbol-hiding as well as related
macro names and some internal variables used for them.

Related configuration file preprocessor symbols named to
CARES_SYMBOL_HIDING and CARES_SYMBOL_SCOPE_EXTERN.

0d9f14f5c1 Initial step towards the ability to reduce c-ares exported symbols 
based on the 'visibility' attribute for GNUC and __global for Sun
compilers, taking also in account __declspec function decoration
for Win32 and Symbian DLL's.

Introducing configure options --enable-hidden-symbols and
--disable-hidden-symbols following libcurl's naming.

f49427d364 Use *_CHECK_PATH_SEPARATOR_REQUIRED to ensure that *_CHECK_PATH_SEPARATOR

04e8ff84fe Our _AS_PATH_SEPARATOR_PREPARE override is now m4_defun'd instead of m4_define'd 
due to autoconf 2.64 m4_require'ing it in _AS_SHELL_SANITIZE indirectly through
_AS_PATH_WALK.
