Fixed lots of issues with installing a low-caps version of fshell from SIS file.
* Fixed issue in CCommandFactory whereby some APIs like GetCommandInfoL could trigger allocations on the wrong heap or signals to the wrong thread. The symptoms were often seen as a crash in the which_00 thread when running ciftest.
* Lots of build fixes for when FSHELL_PROTECTED_UIDS isn't defined and when all capabilities aren't available.
* Added new platform.mmh macro FSHELL_OPEN_SIGNED.
* Open signing of fshell SIS files is now supported for production S60 handsets. Build fshell with the FSHELL_OPEN_SIGNED macro defined (and without defining FSHELL_CAP_ALL or FSHELL_PROTECTED_UIDS) in your platform.mmh and submit \epoc32\fshell\fshell.unsigned.sis to https://www.symbiansigned.com/app/page/public/openSignedOnline.do . The following commands are not available when using Open Signing due to Platform Security restrictions: fdb; kerninfo; chunkinfo; svrinfo; objinfo; sudo; fsck; localdrive; ramdefrag; readmem; reboot; setcritical; setpriority. Others such as chkdeps, e32header, ps, and fshell itself will run but in a restricted capacity (for example, fshell will no longer allow you to modify files in the \sys\bin directory).
* Removed commands objinfo, svrinfo, chunkinfo, readmem, fsck completely when memory access isn't present - previously they would still appear in the help but would give an error if you tried to run them.
These two executables exists to allow fshell to eclipse the ROM based "econs.dll". This can't be done
within the .SIS file because the app installer doesn't allow ROM files to be eclipsed.
fshell_inst.exe copies "<install_drive>:\sys\bin\iocons.dll" to "<install_drive>:\sys\bin\econs.dll".
It is launched by the tool-kit .SIS file at install time.
fshell_uinst.exe deletes "<install_drive>:\sys\bin\econs.dll".
It is launched by the tool-kit .SIS file at uninstall time.
