Updated rudiments to 0.29.

Changes since 0.28.2:
added check for whether SSL_read/write takes void * or char * parameter
added _XOPEN_SOURCE to filedescriptorincludes.h for sys/socket for irix
added collapse argument to charstring::split
added configure test for -Wall
switched lots of:
		char	a[charstring::length(b)];
	to:
		char	*a=new char[charstring::length(b)];
		...
		delete[] a;
	to improve compiler compatibility
removed #ifdef __GNUC__ around static variable definitions, I'll add
	#ifndefs for compilers that don't allow them (like SCO's) if
	necessary
added -D__EXTENSIONS__ to CPPFLAGS
added charstring::escape/unescape
defaulted zeropadding to 1 rather than 0, I'm not sure if it's a bug
	in glibc or not, but printf("%0*lld\n",0,(int64_t)0); prints
	nothing rather than 0, but printf("%0*ld\n",0,(int32_t)0);
	prints 0.  Using 1 instead of 0 for the number of 0's works
	in all cases.
solaris's strchr/strrchr return const char *,
	so I made charstring::findFirst/findLast return const char *
use snprintf's rather than sprintf's now
uses fchmod/fchown rather than chmod/chown now
made envelope classes out of all classes
added a configure test for ftok that takes a char * argument
switched a bunch of AC_TRY_LINK's to AC_TRY_COMPILE's in configure
	script
configure script does less work looking for getpwnam_r and cousins now
if pthread libs can't be found, configure also tries just plain -pthread
added #ifdefs for individual POSIX_FADV_* and MADV_* macros
in configure script, for cygwin, tests for w32api files and functions
	are omitted
configure tests for strtoll/strtoull now
configure tests for caddr_t types for all mmap-related functions
	individually now
unsupported memorymap methods return false now rather than not existing
added -pthread when compiling as well as linking
fixed a time-remaining-related bug in snooze class
fixed a bug where the date/time string buffer could easily be overrun
