hostinfo_unix.cpp

- STILL WORK TO BE DONE TO GET locale STUFF INSTALLED PROPERLY!!!
- Update to libtool 1.5.24
- build environment:  Major automake changes that I've been warning about
  for some time.
- Now uses libtool to build libraries.
- Builds separate boinc_fcgi and sched_fcgi libraries for use with 
  FCGI server components.
- New macro "BOINC_CHECK_LIB_WITH" that executes a "AC_CHECK_LIB" on
  a library only if --with-libname[=DIR] is specified on the configure
  command line.  This is to allow inclusion of libraries when the 
  ssl, gtk, wxWidgets, or other configuration is incorrect for static
  libraries.
- Added a lot of "--with-*" for some libraries that might be required for
  static builds.
- The sea directory has been moved to packages/generic.  Changes to sea
  and the associated scripts might be required to better make use of the
  staging mechanism and shared libraries.
- Fixed includes of boinc_fcgi.h in many files.
- Fixed places where FCGI_FILE needs to be used implicitly.
- Fixed missing define of _SC_PAGESIZE on hosts that define only
  _SC_PAGE_SIZE.
- Moved build of boinc_cmd (and source file) from lib to client
