revlog: break up compression of large deltas

Python's zlib apparently makes an internal copy of strings passed to
compress(). To avoid this, compress strings 1M at a time, then join
them at the end if the result would be smaller than the original.

For initial commits of large but compressible files, this cuts peak
memory usage nearly in half.

Mercurial's documentation is currently kept in ASCIIDOC format, which
is a simple plain text format that's easy to read and edit. It's also
convertible to a variety of other formats including standard UNIX man
page format and HTML.

To do this, you'll need to install ASCIIDOC:

 http://www.methods.co.nz/asciidoc/

To generate the man page:

 asciidoc -d manpage -b docbook hg.1.txt
 xmlto man hg.1.xml

To display:

 groff -mandoc -Tascii hg.1 | more

To create the html page (without stylesheets):

 asciidoc -b html4 hg.1.txt

(older asciidoc may want html instead of html4 above)
