Add support for -boot flag, which allows in-tree execution of Ur/Web The boot flag rewrites most hardcoded paths to point to the build directory, and also forces static compilation. This is convenient for developing Ur/Web, or if you cannot 'sudo make install' Ur/Web. The following changes were made: * Header files were moved to include/urweb instead of include; this lets FFI users point their C_INCLUDE_PATH at this directory at write <urweb/urweb.h>. For internal Ur/Web executables, we simply pass -I$PATH/include/urweb as normal. * Differentiate between LIB and SRCLIB; SRCLIB is Ur and JavaScript source files, while LIB is compiled products from libtool. For in-tree compilation these live in different places. * No longer reference Config for paths; instead use Settings; these settings can be changed dynamically by Compiler.enableBoot () (TODO: add a disableBoot function.) * config.h is now generated directly in include/urweb/config.h, for consistency's sake (especially since it gets installed along with the rest of the headers!) * All of the autotools build products got updated. * The linkStatic field in protocols now only contains the name of the build product, and not the absolute path. Future users have to be careful not to reference the Settings files to early, lest they get an old version (this was the source of two bugs during development of this patch.)

adamc@1141 12 # These exist entirely to fool aclocal when bootstrapping libtool.
adamc@1141 13 #
adamc@1141 14 # In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
adamc@1141 15 # which have later been changed to m4_define as they aren't part of the
adamc@1141 16 # exported API, or moved to Autoconf or Automake where they belong.
adamc@1141 17 #
adamc@1141 18 # The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
adamc@1141 19 # in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
adamc@1141 20 # using a macro with the same name in our local m4/libtool.m4 it'll
adamc@1141 21 # pull the old libtool.m4 in (it doesn't see our shiny new m4_define
adamc@1141 22 # and doesn't know about Autoconf macros at all.)
adamc@1141 23 #
adamc@1141 24 # So we provide this file, which has a silly filename so it's always
adamc@1141 25 # included after everything else. This provides aclocal with the
adamc@1141 26 # AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
adamc@1141 27 # because those macros already exist, or will be overwritten later.
adamc@1141 28 # We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
adamc@1141 29 #
adamc@1141 30 # Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
adamc@1141 31 # Yes, that means every name once taken will need to remain here until
adamc@1141 32 # we give up compatibility with versions before 1.7, at which point
adamc@1141 33 # we need to keep only those names which we still refer to.
adamc@1141 34
adamc@1141 35 # This is to help aclocal find these macros, as it can't see m4_define.
