* nearly all C files: change includes for relative paths.
* lasso/id-wsf/id_wsf.h, lasso/id-wsf-2.0/id_wsf_2.h: add top level
public include files for ID-WSF 1.0 and ID-WSF 2.0.
* lasso/id-ff/server.*, lasso/id-ff/session.*, lasso/id-ff/identity.*:
remove most of the code related to ID-WSF and push into
lasso/id-wsf/id_ff_extensions.* and lasso/id-wsf-2.0/identity.c,
lasso/id-wsf-2.0/server.c, lasso/id-wsf-2.0/session.c.
* lasso/id-wsf-2.0/saml2_login.c,
lasso/id-wsf-2.0/saml2_login_private.h: same change but for ID-WSF
2.0 support in SAML2 SSO profile.
* lasso/saml-2.0/assertion_query.c:
use new code in SAML 2.0 profile.c to parse requests and decrypt
nameid, chains calls so that error are kept but all actions are
accomplished anyway (if first call fails, keep the error but continue
the processing, then at end return the first returned error).
* lots of files: Explicitely set all field of initialized structures,
in order to remove -Wno-missing-field-initilizers from needed
compiler options when using -Wall -Wextra.
