Events: Disable fixed event for runtime invocations from hardware reduced platforms.

It is reported that on Asus T100, Linux RTC driver still invokes ACPICA
fixed event APIs while the platform is hardware reduced. This patch makes
such APIs no-ops during runtime to fix this issue. Lv Zheng.

Applications: Enable USE_NATIVE_ALLOCATE_ZEROED environment for all applications.

We now safe to enable USE_NATIVE_ALLOCATE_ZEROED for all applications as
there are implementations in oswinxf.c, osunixxf.c and osefixf.c. Lv Zheng.

Clib: Add porting layer for print APIs.

This patch:
1. Adds AcpiUtVprintf()/AcpiUtPrintf() support.
2. Adds default stdout for AcpiUtFileVprintf()/AcpiUtFilePrintf().
3. Adds wrapper layer for AcpiUtSnprintf()/AcpiUtVsnprintf(),
   AcpiUtFileVprintf()/AcpiUtFilePrintf() and
   AcpiUtVprintf()/AcpiUtPrintf() and converts their usages into the
   invocations of the wrapper layer.
Note that this patch doesn't enable the print APIs for OSPMs that do not
have ACPI_USE_SYSTEM_CLIBRARY defined before fulling testing the
implementations. Lv Zheng.

Applications: Fix a potential issue that help messages may be dumped to AcpiGbl_DebugFile.

There is an issue for usage macros, if an command line option changed
AcpiGbl_DebugFile, then the follow up usage may errornously dumped to the
debug file.
This is just a bug in theory, because currently AcpiGbl_DebugFile can only
be modified by acpibin and acpiexec. Currently this will not trigger such
issue because:
1. For acpibin, AcpiGbl_DebugFile will be modified by "-t" option and the
   program exit after processing this option without dumping help message
   or other error options.
2. For acpiexec, AcpiGbl_DebugFile will only be modified by the open
   command, which happens after parsing the command line options, so no
   help message will be dumped into the debug file.
But maintaining this logic is difficult, so this patch modifies
AcpiOsPrintf() into ACPI_PRINTF() for usage macros so that the help
messages are ensured to be dumped to the stdout. Lv Zheng.

EFI: Fix build errors by adding component/module definitions.

There are build errors for ACPI_DEBUG_OUTPUT enabled tools. This is because

Clib: Add AcpiOsGetFileCharacter()/AcpiOsPutFileCharacter() to improve portability.

This patch added two new OSLs:
1. AcpiOsGetFileCharacter() as a replacement of fgetc()/getc().
2. AcpiOsPutFileCharacter() as a replacement of fputc()/putc().
For Unix/Windows environments, these 2 APIs are implemented using
fgetc()/fputc(). For EFI environment, they are implemented using
AcpiOsReadFile()/AcpiOsWriteFile().

Note in this patch, ACPI_FILE_IN is simply defined as NULL for EFI
environment. Its EFI support should be implemented by further patches.

Common: Modify string/memory/file libc invocations in AcpiOsGetLine() into c library wrappers to improve portability.

This patch cleans up AcpiOsGetLine() by replacing the following libc
invocations into the c library wrappers:
1. strlen -> ACPI_STRLEN
2. strcpy -> ACPI_STRCPY
3. strtoul -> ACPI_STRTOUL
4. strcpy -> ACPI_STRCPY
5. memmove -> ACPI_MEMMOVE
6. memset -> ACPI_MEMSET
7. fprintf -> ACPI_FPRINTF
8. putchar -> AcpiOsPutFileCharacter(ACPI_FILE_OUT)
9. getchar -> AcpiOsGetFileCharacter(ACPI_FILE_IN)
No functional changes for Unix/Windows environments. Yizhe Wang.
