ISSUE: 6932
TITLE: GTT's pages are not released while dropping it
DESCRIPTION:
We extract value of config parameter 'TempTableDirectory' in order to get directory where GTT data are stored.
If this parameter is undefined then we query environment variables: FIREBIRD_TMP; TEMP and TMP - and stop after
finding first non-empty value in this list. Name of this folder is stored in GTT_DIR variable.
Then we create GTT and add some data in it; file 'fb_table_*' will appear in <GTT_DIR> after this.
We have to obtain size of this file and invoke os.path.getsize(). Result will be NON-zero, despite that Windows
'dir' command shows that this file has size 0. We initialize list 'gtt_size_list' and save this size in it as
'initial' element (with index 0).
After this, we make loop for <ITER_COUNT> iterations and do on each of them:
* drop GTT;
* create GTT (with new name);
* add some data into just created GTT
* get GTT file size and add it to the list for further analysis (see 'gtt_size_list.append(...)')
Finally, we scan list 'gtt_size_list' (starting from 2nd element) and evaluate DIFFERENCE between size of GTT file
that was obtained on Nth and (N-1)th iterations. MEDIAN value of this difference must be ZERO.
NB-1.
BEFORE this ticket was fixed, size of GTT grew noticeably only for the first ~10 iterations.
This is example how size was changed (in percents):
26.88
34.92
12.69
19.84
11.91
10.64
14.43
8.40
7.75
For big numbers of ITER_COUNT values quickly tend to zero.
AFTER this fix size is changed only for 2nd iteration (and not in every measure), for ~6%.
All rest changes (startingfrom 3rd measure) must be zero.
NB-2. Test implemented for Windows only: there is no ability to get name of GTT file on Linux
because all such files marked as deleted immediately after creation.

NOTES:
[20.06.2022] pzotov
Confirmed bug on 3.0.6.33301; 5.0.0.169.
Checked on WINDOWS builds: 3.0.8.33535, 4.0.1.2692, T5.0.0.509
