Isolation of udev code from remaining systemd

This commit is a first attempt to isolate the udev code from the
remaining code base.  It intentionally does not modify any files
but purely delete files which, on a first examination, appear to
not be needed.  This is a sweeping commit which may easily have
missed needed code.  Files can be retrieved by doing a checkout
from the previous commit:

 git checkout 2944f347d0 -- <filename>

-                <para><function>sd_is_fifo()</function> may be called
-                to check whether the specified file descriptor refers
-                to a FIFO or pipe. If the <parameter>path</parameter>
-                parameter is not NULL, it is checked whether the FIFO
-                is bound to the specified file system path.</para>
-
-                <para><function>sd_is_socket()</function> may be
-                called to check whether the specified file descriptor
-                refers to a socket. If the
-                <parameter>family</parameter> parameter is not
-                AF_UNSPEC it is checked whether the socket is of the
-                specified family (AF_UNIX, AF_INET, ...). If the
-                <parameter>type</parameter> parameter is not 0 it is
-                checked whether the socket is of the specified type
-                (SOCK_STREAM, SOCK_DGRAM, ...). If the
-                <parameter>listening</parameter> parameter is positive
-                it is checked whether the socket is in accepting mode,
-                i.e. <function>listen()</function> has been called for
-                it. If <parameter>listening</parameter> is 0, it is
-                checked whether the socket is not in this mode. If the
-                parameter is negative, no such check is made. The
-                <parameter>listening</parameter> parameter should only
-                be used for stream sockets and should be set to a
-                negative value otherwise.</para>
-
-                <para><function>sd_is_socket_inet()</function> is
-                similar to <function>sd_is_socket()</function>, but
-                optionally checks the IPv4 or IPv6 port number the
-                socket is bound to, unless <parameter>port</parameter>
-                is zero. For this call <parameter>family</parameter>
-                must be passed as either AF_UNSPEC, AF_INET, or
-                AF_INET6.</para>
-
-                <para><function>sd_is_socket_unix()</function> is
-                similar to <function>sd_is_socket()</function>, but
-                optionally checks the AF_UNIX path the socket is bound
-                to, unless the <parameter>path</parameter> parameter
-                is NULL. For normal file system AF_UNIX sockets set
-                the <parameter>length</parameter> parameter to 0. For
-                Linux abstract namespace sockets set the
-                <parameter>length</parameter> to the size of the
-                address, including the initial 0 byte and set
-                <parameter>path</parameter> to the initial 0 byte of
-                the socket address.</para>
-
-                <para><function>sd_is_mq()</function> may be called to
-                check whether the specified file descriptor refers to
-                a POSIX message queue. If the
-                <parameter>path</parameter> parameter is not NULL, it
-                is checked whether the message queue is bound to the
-                specified name.</para>

-                a positive return value is returned, otherwise

-                <para>These functions are provided by the reference
-                implementation of APIs for new-style daemons and
-                distributed with the systemd package. The algorithms
-                they implement are simple, and can easily be
-                reimplemented in daemons if it is important to support
-                this interface without using the reference
-                implementation.</para>
-
-                <para>Internally, these function use a combination of
-                <filename>fstat()</filename> and
-                <filename>getsockname()</filename> to check the file
-                descriptor type and where it is bound to.</para>
-
-                <para>For details about the algorithms check the
-                liberally licensed reference implementation sources:
-                <ulink url="http://cgit.freedesktop.org/systemd/systemd/plain/src/libsystemd-daemon/sd-daemon.c"/>

-
-                <para><function>sd_is_fifo()</function> and the
-                related functions are implemented in the reference
-                implementation's <filename>sd-daemon.c</filename> and
-                <filename>sd-daemon.h</filename> files. These
-                interfaces are available as shared library, which can
-                be compiled and linked to with the
-                <literal>libsystemd-daemon</literal>

-                file. Alternatively, applications consuming these APIs
-                may copy the implementation into their source
-                tree. For more details about the reference
