Hao Wu 02263214ef MdePkg/BaseLib: Add safe string functions [U|A]StrnTo[A|U]StrS
Add the following 2 APIs:
UnicodeStrnToAsciiStrS
AsciiStrnToUnicodeStrS

These APIs are used to enhance APIs UnicodeStrToAsciiStrS and
AsciiStrToUnicodeStrS (without 'n' in names) by:
1. Adds an input parameter 'Length' to specify the maximum number of
Ascii/Unicode characters to convert.
2. Adds an output parameter 'DestinationLength' to indicate the number of
Ascii/Unicode characters successfully converted.

Hao Wu ea2e092186 MdePkg/BaseLib: Enhance the return value for string to uint functions
For the following 8 APIs in MdePkg/BaseLib:
[Ascii]StrDecimalToUintn
[Ascii]StrDecimalToUint64
[Ascii]StrHexToUintn
[Ascii]StrHexToUint64

They will ASSERT for DEBUG build when the input string exceeds the range
of UINTN/UINT64. However, for RELEASE build, incorrect value will be
returned.

This commit refines those APIs to direcly call their enhanced counterparts
(with trailing 'S' in API names) so as to remove those exceed-range ASSERT
checks and to make those APIs to return MAX_UINTN/MAX_UINT64 instead.

Hao Wu d8af3301a6 MdePkg/BaseLib: Add safe string functions that convert str to value
Add the following 8 APIs:
[Ascii]StrDecimalToUintnS
[Ascii]StrDecimalToUint64S
[Ascii]StrHexToUintnS
[Ascii]StrHexToUint64S

These safe version APIs are used to enhance their counterpart (APIs
without trailing 'S' in function names).

These safe version APIs perform checks to the input string and will return
relative status to reflect the check result:
When the input string exceeds the range of UINTN/64, these APIs will
return RETURN_UNSUPPORTED and store MAX_UINTN/64 in the output data.
When no conversion can be performed for the input string, these APIs will
return RETURN_SUCCESS and store 0 in the output data.

The optional parameter 'EndPointer', if provided, will point to the
character that stopped the scan.

Hao Wu 6a62309459 MdePkg BaseLib: API PathRemoveLastItem not handle root paths properly
https://bugzilla.tianocore.org/show_bug.cgi?id=239

When the input path for API PathRemoveLastItem() is a root path like
'fs0:\', the API will return TRUE (indicating a directory or file was
removed from the path) and modifies the path to 'fs0:'. In fact, there's
no directory or file removed in the above case.

This commit adds additional check to resolve this issue and modifies the
API's description to make it more straightforward.

Ruiyu Ni 54b1e0ec81 MdePkg: Enhance PathRemoveLastItem() to support "FS0:File.txt"

and removes the string after that.
But when the path is like "FS0:File.txt" which doesn't contain
backslash, the function cannot work well.
The patch enhances the code to look for very last backslash or
colon to support the path which doesn't contain backslash.
