try to interpret it. Single quotes just passes it along to the remote
side. This should fix the nightly test failures with Hydra.

for simple programs.

passing it to the proxy. Some environment variables (e.g., some of the
environment associated with the gnome keyring on my laptop) have spaces
in their values, causing -genvall to break. This commit fixes it and
makes -genvall default.

that directory in the executed command. Right now, either version should
work, but the newer model is better when we do hierarchical proxies. As
a side-effect, we do not have to use sh within ssh anymore, since we
have a single command executed now.

as the program causing the value to be overwritten. Moved all macros
that declare variables as functions as a good programming practice.

[svn-r3998] Squashing several compile warnings in Hydra. Also made the demux engine independent of the central Hydra handle so it can be used by the proxy more cleanly.

part of the code and can be used in any process/function.

be changed. We no longer have auto-incrementing and static variables. The
program logic takes care of assigning the right values for the variables.

stdin. Also, the interface between the proxy and the boot-strap server
is broken; so a proxy has no way to launch more proxies. Thus, only a
one-level hierarchy of proxies is supported right now.

[svn-r3560] Move the handle structure from the control system to the top-level hydra code. This commit only contains structural changes, i.e., moving data structures and functions to different layers (with appropriate renaming to match the layer naming convention).

[svn-r3506] Get rid of explicit FUNCNAME definitions for each function and use the compiler's definition where supported.

[svn-r3440] Several fixes and cleanups to the bootstrap signal handling. The return status is still not correct, but it's not clear what the return status should be.
