Changed llassettype dictionary table to enable linking to most item types.

When you create a link to a notecard, you'll no longer open the notecard.

EXT-7077 : Enable paste as link for folders

Took out code that was stopping paste for god-mode only.  Now everyone can do it.
Corrected a bool logic error for protected folder restrictions.

Various fixes for multi-attachments support.  Ported over from https://hg.lindenlab.com/seraphlinden/seraph-viewer-for-server-1.40/

Change Linux fasttimer implementation back to RDTSC - using a reliable syscall was REALLY chewing CPU time.  Sigh.  I didn't realize how incredibly often this gets called.  So, back to the assembly.
But be more careful with CPU clock count on linux, so the fasttimer values are much more accurate than they were the last time we were with RDTSC, in absolute terms - back in the right order of magnitude anyway.

Also change many instances of Mhz to MHz.
Also some minor comment fixes.

Fixed major bug EXT-6682 (Emptying Lost & Found Folder can crash Viewer2.0 if recent item was added)

Reason: a pointer to renamed item was not nullified in Folder View when rename control lost focus.

Fix: updated focus lost callback to nullify the pointer to renamed item. Had to made this callback non-static to have access to Folder View's member pointer.

Also made "New..." menu items disabled for Lost & Found folder.

Fixed EXT-6790(major) - Limit to amount of text output to script error/warning window is to limited.
Could not find history for floater_script_debug_panel.xml. Looks like current max_length="10000" was randomly picked as a reasonable value at some point of viewer-2-0 development.
Using viewer-1-23 value for max_length - "2147483647"

Fixed normal EXT-6812 ([TRUNCATION] APARIENCIA window > Forma > Boca > Labios: prominec. \"Labios: prominenc\" should be \"Labios: prominencia\".)

- There was two reasons:
1. Uninitialized variable in llsliderctrl.(h/cpp) that contains label size. This variable take part in calculation of TextBox size of label.
2. Font of 'label string' and text box was different. This causes wrong calculation of 'label string' length.

The reason: LLCallDialogManager did not disconnect from "voice channel state changed" signal on channel in previous session.
    Thus when old channel changes state from STATE_HUNG_UP to STATE_CALL_STARTED there is invalid pointer to session in connected LLCallDialogManager::onVoiceChannelStateChanged callback before current voice channel is changed and pointer to session becames valid.

Fix: add storing of connection to signal in voice channel from previous session and disconnect it before connecting to channel in current session.
