Corinna Vinschen 9dae73edb8 Cygwin: fix regression in O_TMPFILE | O_EXCL case
The new proc fd code accidentally allowed to linkat an O_TMPFILE
even if the file has been opened with O_EXCL.  This patch fixes it.

Corinna Vinschen c76468182b Cygwin: pinfo: add method to send a serialized path_conv and HANDLE
To allow reopening a file open in another process by HANDLE, introduce
a matching file_pathconv method, taking a file descriptor as parameter.
The result is a serialized path_conv and a HANDLE value.  The HANDLE is
valid in the foreign process and MUST be duplicated into the target
process before usage.

Erik M. Bray 578bbc3a29 Add a _pinfo.environ() method analogous to _pinfo.cmdline(), and others.
Returns the process's environment concatenated into a single block of
null-terminated strings, along with the length of the environment block.

Adds an associated PICOM_ENVIRON commune_process handler.

__uint32_t in declaration.

argument.  Use information from argument rather than reading from another pipe.
Synchronize with other process's commune event.
(_pinfo::commune_request): Rename from commune_send.  Change DWORD to __uint32
in argument.  Fill out information in new siginfo_t element and rely on
extended operation of sig_send rather than trying to deal with synchronization
issues here.  Use process handle and read pipe information filled out by
sig_send to gather information from the other process.
* sigproc.cc (sig_send): Take special action if "communing" to ensure
synchronization with the other process and to return information about the
other process to the caller.
(talktome): Accept a siginfo_t and handle arguments.  Read additional
information from the signal pipe when _si_commune._si_code has the
PICOM_EXTRASTR flag set.
(wait_sig): Pass the transmitted siginfo_t struct and the pipe handle to
talktome.  Close pipe read handle as soon as possible after we detect that
we're exiting.
