LZma SDK minor fix for compatibility with android NDK (just add one include)

[Gilles Vollant]

android jdk need include string.h to use memset

so in
lzma_sdk/C/Ppmd7.c
I include string.h in addition to memory.h

jni/../../PatchClient/difstrm/lzma_sdk/C/Ppmd7.c: In function 'Ppmd7_Construct':
jni/../../PatchClient/difstrm/lzma_sdk/C/Ppmd7.c:73:3: warning: incompatible implicit declaration of built-in function 'memset' [enabled by default]
memset(p->NS2BSIndx + 2, (2 << 1), 9);
^
jni/../../PatchClient/difstrm/lzma_sdk/C/Ppmd7.c: In function 'RestartModel':
jni/../../PatchClient/difstrm/lzma_sdk/C/Ppmd7.c:289:3: warning: incompatible implicit declaration of built-in function 'memset' [enabled by default]
memset(p->FreeList, 0, sizeof(p->FreeList));
^

replace

include <memory.h>

by

include <memory.h>

include <string.h>

[Igor Pavlov]

I suppose that we don't need <memory.h>, if we use <string.h>.
Am I right?

[İsmail Dönmez]

Yes, string.h defines memset.
