test: adjusted to latest changes.

msgio: added missing change.

msgio: improved GWEN_MSG, added convenience functions.

msgio: introduce GWEN_MsgEndpoint_GetNextMessageId()

Use pkgconf for gpg-error build flags

On some build systems the old automake macro AM_PATH_GPG_ERROR doesn't work
because the binary gpg-error-config no longer exists. As a gpg-error.pc file is
available, let's switch to this more contemporary approach to determine the...

Fixed call to readlink().

readlink() doesn't append a NULL!!

gsa: fixed handling of symbolic links.

incremented version.

gwenbuild: use lstat if possible (otherwise symbolic links will be resolved).

gwenbuild: also install symbolic links for libs.

Incremented version.

README: remove var from documentation (no longer used).

Added GWENHYWFAR_CB to function implementations also (seems to be required from MinGW64, see #306)

Use GWEN_Text_strndup() instead of strndup (the latter is not available with MinGW64).

Added license info for portable_endian.h (public domain).

Fixed a bug in GWEN_Date (day numbering starts at 1, not zero).

Use new "portable_endian.h" instead of endian.h

Added "portable_endian.h" from https://gist.github.com/panzi/6856583

Frame error messages from gcc or other called tools with
"entering directory ..." and "leaving directory ..." to improve error
handling when calling gwbuild from an IDE (or in my case FTE).

Those lines help the IDE to locate files (e.g. when there are errors in...

incremented version.

prepared release 5.11.1beta.

make list types typesafe.

"typedef GWEN_LIST1 t##_LIST" will not allow to detect when a wrong list
type is used as long as any list type is used. That will most likely lead
to undefined behaviour.

Maybe we will need to increment the major build version because of this.

gwen_buffer: corrected use of va_start and va_end.
