tee(1): explicitly check read(2) return value for 0 and -1

tee(1): increase I/O buffer size from 8KB to 64KB

64KB strikes a good balance between space and time on today's
machines. Buffers smaller than 64KB waste more time in userspace
traveling to and fro

tee(1): increase I/O buffer size from 8KB to 64KB

64KB strikes a good balance between space and time on today's
machines. Buffers smaller than 64KB waste more time in userspace
traveling to and from the kernel. Buffers larger than 64KB do I/O a
bit faster, but the performance improvements rapidly diminish at a
steep memory cost.

Discussed with millert@ and deraadt@. Positive feedback from Geoff
Steckel.

tee(1): use idiomatic write loop

tee(1) handles partial writes correctly, but the more idiomatic write
loop is shorter and easier to audit than this heterodox approach.
