Raw Blame History

Fix a const-related compiler warning produced by the "execve" wrapper.
Move network related wrappers to separate files, for SOCKS support.
Fix some things so that it will compile under FreeBSD-3.0.
Add missing wrappers for various system calls.
Fix numerous argument declarations to agree with their prototypes.
Fix the wrapper for ftruncate so that it deals properly with the 64-bit
arguments.
