Adopting Swift File Operations

Migrate existing C code to Swift, using the file operations provided by the System module.

Overview

The C functions for file operations map to Swift as follows:

close ⟶ close()
lseek ⟶ seek(offset:from:)
open ⟶ open(_:_:options:permissions:retryOnInterrupt:)
pread ⟶ read(fromAbsoluteOffset:into:retryOnInterrupt:)
pwrite ⟶ write(toAbsoluteOffset:_:retryOnInterrupt:)
read ⟶ read(into:retryOnInterrupt:)
write ⟶ write(_:retryOnInterrupt:)
