omrzk 666a8ef7cd Honor the symbolic link option when copying files 
Inspect source links without following them when COPYFILE_SYM is requested, before rejecting directories. This makes the documented option recreate link text instead of copying the referent, including dangling and directory links. Preserve requested link timestamps and report link-creation errors without overwriting the destination. Cover direct calls, destination directories, normal dereferencing and the existing rsync file caller.

Joachim Wiberg dff88a622d Merge pull request #22 from omrzk/fix/copy-binary-file-streams 
Preserve binary data when copying file streams

omrzk 2dfc02e67d Preserve binary data when copying file streams 
Copy the bytes returned by fread instead of treating each input chunk as a NUL-terminated string. Preserve the public stream positions and report read and write failures rather than returning success after a partial copy. Add binary boundary, current-position, native pipe error and full-device regression coverage.

Joachim Wiberg b69d8a6013 Fix copyfile() not preserving source mode with restrictive umask 
copyfile() passes the source mode to open(2), which applies the umask,
so a 0644 file copied with umask 0027 ends up 0640.

Apply the source mode with fchmod() after creating the destination.

Joachim Wiberg e874608b76 Fix mkpath() ignoring mode when umask is more restrictive 
mkpath(dir, 0755) with umask 0027 silently creates a 0750 directory,
since mkdir(2) applies the umask to the requested mode.  Callers pass
an explicit mode and expect exactly that.

Apply the mode with chmod() after each successful mkdir().

Joachim Wiberg 958502d982 Fix memory leak in which() on realloc() failure 
Avoid leaking memory when realloc() fails by using a temporary pointer
and only updating the original on success. Also remove redundant NULL
check before free().

Joachim Wiberg 9bfe54f959 pidfile(): ensure prefix path ends with slash 
For some builds using Buildroot, the system default _PATH_VARRUN did not
include a trailing slas '/', which cause the pidfile() function to fail.

Example:
  pidfile("arg") => "/var/runarg.pid"

Since the __pidfile_path can be overridden we add a check if that prefix
path ends with '/', if not we add one in the path composition.

Joachim Wiberg 92bb0ca399 runbg: new helper function inspired by the Infix project 
The runbg() function is a delayed execvp() that has double-forked to the
background (to not create zombies).  It is useful for running commands
in the background for APIs that need to return a reply, e.g. a NETCONF
RPC to reboot the system.

Compared to the original in Infix, this version double forks to reparent
itself to PID 1 (init), closes all open files, including stdio.
