Up until recently, CPP has been a list of space-separated words, with no
quotes, backslashes or other characters with special meaning to a shell.
However, as of 8fad2cda93, (escaped) quotes appear in CPP, and the
rudimentary parser in rpcgen is insufficient, since it will leave the
escaped quotes as escaped rather than performing one level of expansion
as would be done by a shell (whether in a script or a Makefile).
Rather than hack around this in all the places RPCGEN_CPP gets set,
implement proper expansion inside rpcgen. Note that this only deals with
a subset of shell syntax, since we don't handle any of:
| & ; < > ( ) $ ` * ? [ # ˜ = %
having special meaning (with the exception of how a backslash behaves
inside double quotes, where \$ means a literal $ inside double quotes
but \a means a literal \a), instead using their literal value, but those
are all reasonable restrictions, and can be worked around by avoiding
their use; what's important is that we get the quoting and splitting
right.
This fixes -Winvalid-pp-token spew during build${libcompat}.

The re-initialisation of idx in the later else branch is a bit hidden,
and results in deviation from the earlier two paths. Use more consistent
code instead to make it abundantly clear what's going on.
In most cases, usage does not return, so mark them as __dead2. For the
cases where they do return, they have not been marked __dead2.

preprocessor to run. Previously, it always ran /usr/bin/cpp, unless you
used the -Y option, and even then you could not set the basename. It
also attempted to run /usr/ccs/lib/cpp for SVR4 compatibility, but this
is obsolete, and has been removed.
Note that setting RPCGEN_CPP to a command with arguments is supported,
though the command line parsing is simplistic. However, setting it to
e.g. "gcc46 -E" or "clang -E" will lead to problems, because both gcc
and clang in -E mode will consider files with unknown extensions (such
as .x) as object files, and attempt to link them.
This could be worked around by also adding "-x c", but it is much safer
to set RPCGEN_CPP to e.g. "cpp46" or "clang-cpp" instead.

The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.
This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.
