[rfa/target/doc] Print less with "set debug target 1"

- Subject: [rfa/target/doc] Print less with "set debug target 1"
This is something that's always bugged me. I wanted to track a problem in
the testsuite using "set debug target 1", but the output was so incredibly
noisy (because of libthread_db) that everything timed out. This patch
changes "set debug target 1" to only print the first line of a memory
transfer, and documents "set debug target 2" to print the whole thing.
Seem OK?

* target.c (debug_to_xfer_memory): If targetdebug is 1, don't
print the whole transfer.

* gdb.texinfo (Debugging Output): Document values for "set debug
target".
