BobCF 2f818ed0fb BaseTools: Replace the sqlite database with list
https://bugzilla.tianocore.org/show_bug.cgi?id=1288

[V2]
Optimize this patch so that it can be easy to review.
This patch is just apply the change to original files while
not create new similar files.

[V1]
This patch is one of build tool performance improvement
series patches.

This patch is going to use python list to store the parser data
instead of using sqlite database.

The replacement solution is as below:

SQL insert: list.append()
SQL select: list comprehension. for example:
Select * from table where field = “something”
->
[ item for item in table if item[3] == “something”]

SQL update: python map function. for example:
Update table set field1=newvalue where filed2 = “something”.
-> map(lambda x: x[1] = newvalue,
   [item for item in table if item[2] == “something”])

SQL delete: list comprehension.

With this change, We can save the time of interpreting SQL statement
and the time of write database to file system

This directory contains the next generation of EDK II build tools and template files.
Templates are located in the Conf directory, while the tools executables for
Microsoft Windows 32-bit Operating Systems are located in the Bin\Win32 directory, other
directory contatins tools source.

1. Build step to generate the binary tools.

=== Windows/Visual Studio Notes ===

To build the BaseTools, you should run the standard vsvars32.bat script
from your preferred Visual Studio installation or you can run get_vsvars.bat
to use latest automatically detected version.

In addition to this, you should set the following environment variables:

 * EDK_TOOLS_PATH - Path to the BaseTools sub directory under the edk2 tree
 * BASE_TOOLS_PATH - The directory where the BaseTools source is located.
   (It is the same directory where this README.txt is located.)

After this, you can run the toolsetup.bat file, which is in the same
directory as this file.  It should setup the remainder of the environment,
and build the tools if necessary.

Please also refer to the 'BuildNotes.txt' file for more information on
building under Windows.

=== Unix-like operating systems ===

To build on Unix-like operating systems, you only need to type 'make' in
the base directory of the project.

=== Ubuntu Notes ===

On Ubuntu, the following command should install all the necessary build
packages to build all the C BaseTools:

  sudo apt-get install build-essential uuid-dev

=== Python sqlite3 module ===
On Windows, the cx_freeze will not copy the sqlite3.dll to the frozen
binary directory (the same directory as build.exe and GenFds.exe).
Please copy it manually from <PythonHome>\DLLs.

The Python distributed with most recent Linux will have sqlite3 module
built in. If not, please install sqlit3 package separately.
