[ANNOUNCEMENT] Updated: setup (2.880)

[Jon Turney]

A new version of Setup, release 2.880, has been uploaded to

   https://cygwin.com/setup-x86.exe     (32 bit version)
   https://cygwin.com/setup-x86_64.exe  (64 bit version)

Changes compared to 2.879:

- "Internet Explorer Proxy Settings" is renamed to "System Proxy Settings".

- Remove support for the syntax "requires: A | B" in setup.ini, which 
calm/upset/genini never generated, and was just treated as "requires: 
A", anyhow.

- Fix a bug where installing a version other than the current version 
the first time a package is installed might lead to it's dependencies 
not being installed.

- Add some progress reporting during preremove and uninstall operations.

- Fix a bug which caused orphaned packages to be omitted from the 
picker. (A regression introduced in 2.878)

- Correctly account for source packages to be installed due to the 
--include-source option in the total amount of data to checksum.

- Rename the category "Misc" to "Orphaned".

- Fix an infinite recursion in the setup.ini parser for "depends:"

- Error recovery in setup.ini parsing is now slightly improved, so the 
same parse error isn't reported multiple times.

- Add the option "--user-agent" to override the user-agent string sent 
in HTTP requests.
(Addresses: https://cygwin.com/ml/cygwin/2012-02/msg00857.html etc.)

- The default user-agent string now contains the setup version.

- Fix that clicking on any column can change "Keep" to "Uninstall".
(Addresses: https://cygwin.com/ml/cygwin/2017-05/msg00525.html)

- Allow click-to-activate in the package list control.

- Improve the unhelpful error message "Can't open (null) for reading: No 
such file".

- Remove some messagebox spam when using file:// protocol URLs for a 
package repository without a compressed setup.ini.

- Some source code cleanups and cruft removal.
