ext: Include libfputils
This changeset includes libfputils from revision bbf0d61d75. This library can be used to convert to and from 80-bit floats and query the type of an 80-bit float, which is needed to support the x87 FPU.

+# SYNOPSIS
+#
+# DX_INIT_DOXYGEN(PROJECT-NAME, DOXYFILE-PATH, [OUTPUT-DIR])
+# DX_DOXYGEN_FEATURE(ON|OFF)
+# DX_DOT_FEATURE(ON|OFF)
+# DX_HTML_FEATURE(ON|OFF)
+# DX_CHM_FEATURE(ON|OFF)
+# DX_CHI_FEATURE(ON|OFF)
+# DX_MAN_FEATURE(ON|OFF)
+# DX_RTF_FEATURE(ON|OFF)
+# DX_XML_FEATURE(ON|OFF)
+# DX_PDF_FEATURE(ON|OFF)
+# DX_PS_FEATURE(ON|OFF)
+#
+# DESCRIPTION
+#
+# The DX_*_FEATURE macros control the default setting for the given
+# Doxygen feature. Supported features are 'DOXYGEN' itself, 'DOT' for
+# generating graphics, 'HTML' for plain HTML, 'CHM' for compressed HTML
+# help (for MS users), 'CHI' for generating a seperate .chi file by the
+# .chm file, and 'MAN', 'RTF', 'XML', 'PDF' and 'PS' for the appropriate
+# output formats. The environment variable DOXYGEN_PAPER_SIZE may be
+# specified to override the default 'a4wide' paper size.
+#
+# By default, HTML, PDF and PS documentation is generated as this seems to
+# be the most popular and portable combination. MAN pages created by
+# Doxygen are usually problematic, though by picking an appropriate subset
+# and doing some massaging they might be better than nothing. CHM and RTF
+# are specific for MS (note that you can't generate both HTML and CHM at
+# the same time). The XML is rather useless unless you apply specialized
+# post-processing to it.
+#
+# The macros mainly control the default state of the feature. The use can
+# override the default by specifying --enable or --disable. The macros
+# ensure that contradictory flags are not given (e.g.,
+# --enable-doxygen-html and --enable-doxygen-chm,
+# --enable-doxygen-anything with --disable-doxygen, etc.) Finally, each
+# feature will be automatically disabled (with a warning) if the required
+# programs are missing.
+#
+# Once all the feature defaults have been specified, call DX_INIT_DOXYGEN
+# with the following parameters: a one-word name for the project for use
+# as a filename base etc., an optional configuration file name (the
+# default is 'Doxyfile', the same as Doxygen's default), and an optional
+# output directory name (the default is 'doxygen-doc').
+#
+# Automake Support
+#
+# The following is a template aminclude.am file for use with Automake.
+# Make targets and variables values are controlled by the various
+# DX_COND_* conditionals set by autoconf.
+#
+# The provided targets are:
+#
+# doxygen-doc: Generate all doxygen documentation.
+#
+# doxygen-run: Run doxygen, which will generate some of the
+# documentation (HTML, CHM, CHI, MAN, RTF, XML)
+# but will not do the post processing required
+# for the rest of it (PS, PDF, and some MAN).
+#
+# doxygen-man: Rename some doxygen generated man pages.
+#
+# doxygen-ps: Generate doxygen PostScript documentation.
+#
+# doxygen-pdf: Generate doxygen PDF documentation.
+#
+# Note that by default these are not integrated into the automake targets.
+# If doxygen is used to generate man pages, you can achieve this
+# integration by setting man3_MANS to the list of man pages generated and
+# then adding the dependency:
+#
+# $(man3_MANS): doxygen-doc
+#
+# This will cause make to run doxygen and generate all the documentation.
+#
+# The following variable is intended for use in Makefile.am:
+#
+# DX_CLEANFILES = everything to clean.
+#
+# Then add this variable to MOSTLYCLEANFILES.
