Fix pg_upgrade, broken by the xlogid/segno -> 64-bit int refactoring.

Browse Source 
The xlogid + segno representation of a particular WAL segment doesn't make
much sense in pg_resetxlog anymore, now that we don't use that anywhere
else. Use the WAL filename instead, since that's a convenient way to name a
particular WAL segment.

I did this partially for pg_resetxlog in the original xlogid/segno -> uint64
patch, but I neglected pg_upgrade and the docs. This should now be more
complete.

the directory <filename>pg_xlog</> under the data directory.
These names are also in hexadecimal and have three parts. The first
part is the <quote>timeline ID</> and should usually be kept the same.
Do not choose a value larger than 255 (<literal>0xFF</>) for the third
part; instead increment the second part and reset the third part to 0.
For example, if <filename>00000001000000320000004A</> is the
largest entry in <filename>pg_xlog</>, <literal>-l 0x1,0x32,0x4B</> will
work; but if the largest entry is
<filename>000000010000003A000000FF</>, choose <literal>-l 0x1,0x3B,0x0</>
