TCP Wrappers: tcpdchk (tcp wrapper configuration checker) and tcpdmatch
(tcp wrapper oracle) warning fixes via edits to the C code files

contrib/tcp_wrappers/fakelog.c
Warnings for each of functions: openlog( ), vsyslog( ), VARARGS( ),
closelog( )
warning: type specifier missing, defaults to 'int' [-Wimplicit-int]
warning: control reaches end of non-void function [-Wreturn-type]
Fixes:
Explicitly added specification of function type to void for each
function, suppressing both warnings for each function listed
contrib/tcp_wrappers/inetcf.c
Warnings:
warning: incompativle redeclaration of library function 'malloc'
note: 'malloc' is a builtin with type 'void *(unsigned long)'
warning: implicit declaration of function 'check_path' is invalid in C99
[-Wimplicit-function-declaration]
Fixes:
Removed redeclaration of malloc on line 21
Included library <stdlib.h> in the code which contains the malloc( )
function in it's library
Included scaffold.h header file in the code that contains check-path( )
function
contrib/tcp_wrappers/scaffold.c
Warnings:
warning: implicitly declaring library function 'exit' with type
'void (int) __attribute__((noreturn))' [-Wimplicit-function-declaration]
note: include the header <stdlib.h> or explicitly provide a declaration
for 'exit'
Fixes:
Included <stdlib.h> in the code which contains the exit( ) function in
it's library
contrib/tcp_wrappers/tcpdchk.c
Warnings:
warning: implicit declaration of function 'getopt' is invalid
in C99 [-Wimplicit-function-declaration]
warning: implicit declaration of function 'atoi' is invalid
in C99 [-Wimplicit-function-declaration]
Fixes:
Included the specific function <getopt.h> library to the code
Included<stdlib.h> to the code which contains the atoi( ) function in
the library
contrib/tcp_wrappers/tcpdmatch.c
Warnings:
warning: implicit declaration of function 'getopt' is invalid in C99
[-Wimplicit-function-declaration]
Fixes:
Included<stdlib.h> to the code which contains the getopt( ) function in
the library

Since our inetd wrapped now, treat all its services as tcpd-prefixed
for tcpdchk

Clean import of TCP-wrappers by Wietse Venema.
Rest of build to follow.
